Species Native Research Paper Example | Topics and Well Written Essays - 500 words
Species Native - Research Paper Example A grown-up green ocean turtle weighs more than 500 pounds. Like all other turtle species, green ocean turtles have a hard structure called shell, whose capacity is to give assurance to the turtle from predators. The piece of the shell that is on the dorsal (posterior is known as the carapace (Green Sea Turtles, n.d.). This bit is heart molded, and is up to 5 feet. It is secured with huge scopes which are called scutes. The ventral piece of the shell that covers the stomach is known as the plastron. The dorsal and ventral parts are associated with one another along the edges through hard-shelled plates which are known as sidelong extensions. The association between the carapace and plastron breaks at the openings for the head, tail and appendages. The distinction between green ocean turtles, land turtles and tortoises is that green ocean turtles can't withdraw their little heads into the shell for additional assurance. The shells of green ocean turtles are light weight and are progres sively evolved when contrasted with shells of land turtles.

Global Environmental Issues Research Paper - 825 Words
Global Environmental Issues (Research Paper Sample) Content: Global Environmental IssuesStudent NameInstitutional AffiliationEthics entails beliefs on the right versus the wrong while values are those things considered to be important (Hartman, 2011). A business has to undertake several obligations to enhance and protect the society in which it functions to be successful. Organizations may exhibit social responsibility towards the natural environment, their stakeholders or through general social welfare (Hartman, 2011). The implementation of this social responsibility can be through ethical compliance, legal compliance or philanthropic giving. In this paper, the primary focus shall be on organizationà ¢Ã¢â ¬s social obligation towards the natural environment.Organizations are under obligations to protect the natural environment. In the United States, the Environmental Protection Agency is tasked with regulating environmental issues and legislation. However, in the international sphere, bodies like United Nations Environmenta l Program are the chief players in this sector. UNEP is aided by local country agencies and other non-profit organizations to achieve its objectives. Despite there being clear set environmental rules and legislation, some organizations have time and again defied them (Hartman, 2011). Defiance of set standards not only exposes humans to hazards and other risks, it also puts the entire ecosystem at stake.Most businesses have expanded to cover international borders to increase their market share. The growth comes with other challenges that need to be addressed. Multinational companies have a social obligation. They have optimally to utilize their power and control of resources in a beneficial manner. Environmental pollution and ethical issues arise when host countryà ¢Ã¢â ¬s environmental regulations are inferior to those in the home nation. Dumping of toxic wastes and other products can open room for pollution if not well addressed. Most multinational organizations have come out as strong protectors of the environment to build their public image and foster relations. However, some have abused their powers and loopholes in the legislation of the host countries to cause environmental pollution (Payne, 1997).The case study of exporting used batteries to Mexico is an example of how multinational companies can abuse their social obligations. Most of the exporters are middle people in the USA who buy old cells and expose them to Mexico. There is increased concern about lead battery hazards more so from the recycling activities. Countries like Mexico have reported an increase in lead poisoning from such activities. The battery export business seems to employ the Friedman doctrine. The traditions allude that a businessà ¢Ã¢â ¬ primary aim is to make a profit as long as it remains within the law regardless of the consequences to society (Hill, 2010).The companies in Mexico predispose their employees to extremely high and toxic amounts of lead. The lead is absorbed by their bodies and accumulates in their bodies to dangerous levels. In the case provided, the blood samples of one of the workers had double the amount of lead believed to induce mental damage. The illustration is an epitome of abuse of the rights of employees. Article 23 of the Universal Declaration of Human rights specifies that a person, among other things, needs to work under the right conditions. The conditions provided by these lead recycling companies are clearly not the ideal for the employee (Hill, 2010).The case study company selected for analysis is Fight Fit Ohio. The company is a service industry that trains martial arts, kickboxing, and self-defense. The business is one that relies on the right environment for the proper instructions for its functions.

Hills Like White Elephants Analysis - 1803 Words
Subject The text ââ¬Å"Letting the air into a relationship: Metaphorical Abortion in ââ¬ËHills Like White Elephantsâ⬠by Wyche David aims at analyzing and synthesizing the short story by Hemingway ââ¬Å"Hills like Whiteâ⬠. The analysis would provide new knowledge to readers of the short story or provide the readers with a new point of view of analyzing it. The subject of the text is to present his ideas on the short story and well as critique other critics who had previously critiqued it. The story illustrates broken relationships of Hemingway and the pain it caused him, which led him to write the short story. The whole text is therefore an analysis and synthesis of the short story written by Hemingway. Thesis The authorââ¬â¢s main argument is that the textâ⬠¦show more contentâ⬠¦Wyche disputes all the critics who suggested that the text was either about whether Jig should carry the pregnancy to a full term or have an abortion. Wyche feels that the text was a metaphor representing pain which comes as a result of an end of a relationship between two people. One of his main ideas was therefore to dispute some of the ideas that critics had put forward in the past and bring forward a new meaning to the short story. As Wyche noted most of the critics saw a metaphor of abortion but failed to see that the abortion could also be used as metaphor to mean something else which in this case means the pain of a breakup. By bringing other criticââ¬â¢s point of view into play, he successfully acknowledges what they wrote and their ideas but also presents him with a point to dispute the same. Even if he does not refuse the ideas produced by earlier critics, the author presents a different poi nt of view from whatever was presented before. Wyche also shows that writers like Hemingway may be influenced by what is going on in their personal life. Wyche also aims to relate Hemingwayââ¬â¢s life and that of the author. Towards the end of the text, Wyche provides a comparison of Hemingwayââ¬â¢s real life and the author and notes that he always had a way of feeding his artistic side from his personal experiences. Hemingwayââ¬â¢s work was a mirror of reality and much of his reality.

Ethical and Legal Practices and Capacity
Question: Severe Exacerbation of his COPD with Dyspnoea on Minimal Exertion. Answer: Introduction: Healthcare professionals are bound to undertake ethical and legal exasperations from patients, associated family and the healthcare administration. The interventions that are to be imparted upon the patient must be in accordance with predilection of the patient and associated family. Furthermore, but such penchant cannot always been considered by the healthcare professionals as in many cases such predilection may not be justifiable. The example of this can be insufficient knowledge towards prevailing health condition and affect to decision due to advanced age, social, cultural, psychosocial and financial factors (Herring, 2014). The report is an analysis on the refusal of treatment and beneficence ethical and legal practices that affects the intervention treatment regulated by the healthcare professionals through the case study of Mr. Gray who is suffering from COPD. This report outlines an overall analysis on maintaining the ethical approach while provisioning the treatment. Furthermore, two ethical and legal practices with the care that are refusal of treatment and beneficence have been undertaken for the analysis of the case study of Mr. Gray. Importance of Ethical Approach: Ethics is a philosophical approach that believes in preventing and safeguarding the moral principles of a human being that are based on their social, cultural, psychosocial, economic and financial experiences. Furthermore, ethics provide an order, recommendation and prevention of the rights of an individual in order to protect them from any misconduct by another human being (Miravitlles et al., 2013). In accordance to this concept, the healthcare professionals conduct and impart the treatment to the patients with distress. Furthermore, keeping this viewpoint in mind, the first establishment of the principles of ethics was conducted by Tom Beauchamp and James Childress in 1985 (Ebbesen Sundby, 2015). Such principles are interrelated and provide the healthcare professionals optimal framework and guidelines for the formulation, implementation and regulation of optimal remedial treatment to the patients. The two chosen ethical and legal practice framework are refusal of treatment and be neficence (Entwistle Watt, 2013). Condition of Patient: Mr. Gray is an old man who is 67 years old and is suffering from Chronic Obstructive Pulmonary Disease (COPD) along with dyspnoea. Additionally, he is suffering from dysphagia, nocturnal pyrexia and dysphasia (Incalzi et al., 2014). Furthermore, he has signs and symptoms such as high temperature, lowered oxygen saturation levels, tachycardia, high respiratory rate, normotensive and pneumonia. Additionally, along with such condition he has severe refusal towards treatment and meeting his family members, other patients in the hospital and staff members of the hospital. Refusal towards treatment is towards the consumption of the medication and undergoing Enteral Feeding. The healthcare professionals are undertaking optimal steps such as providing consent to the family members regarding the treatment require to be imparted to Mr. Gray (Pagano, 2016). Comparison of Refusal of Treatment with the Care: The right to refusal of treatment is the basic right provided to the patient in order to prevent and prohibit the pharmacological and non-pharmacological interventions as per their will. This right preserves the moral ethics, provides protection and privacy during the conduction of the treatment. In addition to this, such right preserves the integrity and decision-making of a patient but unfortunately, this right usually gets misused by the patient having no knowledge on their medical condition. Certain factors such as no awareness, advanced age, influence by social, cultural, ethical and psychosocial experiences and others affects the decision-making of a patient to a large extent. Additionally, this condition locks and prohibits the healthcare professionals from undertaking decisions related to safeguard interventions (Ryan, Callaghan Peisah, 2015). Similar, situation has arisen in case of Mr. Gray who has severe refusal towards pharmacological intervention of paracetamol and conduction of Enteral Feeding through the inserting of nasogastric tube. The evidence based practices need to be implemented such by informing the patient and associated family on the importance of safety of the treatment and the recovery of patient, the required voluntary treatment by the patient are not effective anymore, the benefits or advantages are way more stable and outweighs the associated risks (Loke, 2015). In conclusion to the prevailing scenario, Mr. Gray comes under the case of an adult with capacity that determines the refusal by a patient in order to satisfy themselves irrespective of the degrading repercussions that can originate ahead. Consistent and prolonged refusal by Mr. Gray has led the healthcare professionals to approach Mrs. Gray regarding the imparting of effective intervention. Mrs. Gray is open to such safeguard interventions an d wants her husband to recover as soon as possible. Additionally, under such circumstances the associated healthcare professionals are open to undertake the safeguard interventions as per the consent and approval from Mrs. Gray. Furthermore, the concept of coercion must be separated from this situation as coercion is regarded as invasive and a term usually used for the treatment of the patients suffering from medical conditions but in the case Mr. Gray the treatments are non-invasive and must be conducted in accordance with the approval of Mrs. Gray (Soininen et al., 2014). Conclusively, the procedural measures for the conduction of remedial treatment for Mr. Gray have been undertaken in accordance with the rationale of refusal of treatment. Comparison of Beneficence with the Care: Beneficence is one of the four principles of ethics formulated by Tom Beauchamp and James Childress in 1985 (Ross, 2016). This principle provides effective remedial actions that are essential and required to be implemented to benefit and provide relief to the patient under distress. Beneficence is a broad concept that allows the healthcare professionals to provide effectual concoction of pharmacological and non-pharmacological interventions in accordance with the circumstances, somatic and mental wellbeing of the patient. Such interventions are required to be implemented with the help of experienced skills and high level of knowledge towards the condition and effective interventions (Martela Ryan, 2015). Beneficence principle goes in accordance with the case of Mr. Gray as this ethical approach has provided every possible measure to the healthcare professional for the conduction of the treatment in Mr. Gray. Furthermore, the concept of consent is also attached to the beneficence as consent allows optimal awareness of the existing condition, possible safeguard interventions and their extent of affects on the patient. In accordance with the beneficence, Mr. Gray has been optimally diagnosed and treated well. Furthermore, patient-oriented strategies and protocols have been formulated in respect to different medical conditions occurring in Mr. Gray. Additionally, consent has been implemented in Mrs. Gray regarding the continual refusal towards treatment by his husband. Such communication over consent has provided approval of treatment by Mrs. Gray that legally allows the healthcare professionals to proceed with the treatment irrespective of the approval by Mr. Gray (Corvol et al., 2013). Chronic Obstructive Pulmonary Disorder (COPD) is a condition that affects the lungs and degrades it making the patient incapable enough of breathing (Dharmarajan et al., 2016). Certain signs and symptoms of COPD are wheezing, shortness of breath, severe weakness, coughing and tight chest. Maintaining optimal nutritional level and healthy diet under such condition becomes extremely tough and provision of enteral feeding is undertaken when oral feeding is not possible as in the case of Mr. Gray. The level of nutrients is manually handled by the healthcare professionals (Prince et al., 2015). This is mainly a non-invasive method and is frequently undertaken by various healthcare professionals to provide remedial treatment and has fewer side effects. Provision of nasogastric tube for Mr. Gray will allow optimal levels of nutrients in the body as he is continually refusing for the intake of food orally. Furthermore, optimal level of nutrients will allow the regulation of the antibiotic th erapy in Mr. Gray provided for the treatment of pneumonia and other prevailing severe health condition in him (Reeve et al., 2016). Conclusively, the procedural measures for Mr. Gray in order to conduct remedial treatment have been undertaken in accordance with the beneficence rationale. Conclusion: The right to refusal of treatment was made to preserve the ethical integrity and likings of the patient while it has been manipulated by patients with the help of voluntary and involuntary refusal. This right also provides provision of continuum of care in accordance with the approval by the associated family members. Mr. Gray is an old man who is 67 years old and is suffering from Chronic Obstructive Pulmonary Disorder (COPD), dysphagia, pyrexia, dysphasia, pneumonia, dyspnoea and haemoptysis. Such condition requires consumption of antibiotics orally and intake of optimal healthy diet. Refusal to both has been seen in Mr. Gray in order to satisfy themselves irrespective of competent enough regarding the degrading consequences of the refusal. Symptoms such as shortness of breath, wheezes, weakness and others has led the healthcare professionals to come up with enteral feeding and must be regulated by the approval of Mrs. Gray. Besides this, beneficence also goes along with the case study of Mr. Gray that allows the provision of effective treatment by respecting the ethical and moral integrity of Mr. Gray and his family by not forcing Mr. Gray on consuming oral antibiotic and oral consumption of food. Additionally, another possible method of treatment is enteral feeding that is non-invasive in nature to which patient is again showing refusal. Beneficence allows generating and enhancing the consent of the family members as in this case is Mrs. Gray and proceeding further with the treatment in accordance with the approval by Mrs. Gray.

Water Pollution and Global Warming Essay Example
Water Pollution and Global Warming Paper As a result it plays important roles in ecosystem support, economic development, cultural values and community well-being. Dozens of times a day those of us who live in the industrialized nations of the world enjoy a blessing denied to 75 percent of the world population: abundant supplies of clean water. But water is essential for life on earth. No known organisms can live without it. For centuries water has been used as a dumping ground for human sewage and industrial wastes. Added to them are the materials leached out and transported from and by water percolating through the soil and running off its surface to aquatic ecosystems. Water pollution is degradation of water quality. Any physical, chemical, or biological change in water quality that adversely affects living organisms or makes water unsuitable for desired use can be considered pollution. Thus the term water pollution refers to ââ¬â ââ¬Å"Water contamination by a variety of chemical substances or transportation caused by several nutrients and fertilizers. â⬠ââ¬â Southwest, 1 976 U. S. Department of Health Education and Welfare defines water pollution as ââ¬â ââ¬Å"The adding to water of any substance or he changing of waterââ¬â¢s physical and chemical characteristics in any way which interferes with its use of legitimate purposesâ⬠. At present, water pollution is a major global problem. Everyday many people are dying for water pollution. Now water pollution becomes the leading cause of death diseases. 3 1. 2 Sources of Water Pollution : There are many sources of water pollution. But before knowing that, we need to know that what are the sources of water, and then we will understand how they are becoming polluted. We get water from two sources ââ¬â Surface Water Ground Water Surface Water is fresh water mound on Earthââ¬â¢s surface in streams and rivers, lakes, ponds, reservoirs. Surface waters are replenished by the runoff of precipitation from the land and are therefore considered a renewable, although finite resource.

This water originates as rain or melting snow that seeps into the soil and finds its way down through cracks and spaces in sand, gravel or rock until it is stopped by an impenetrable layer, there it accumulates as groundwater. Surface water and groundwater have often been studied and managed as operate resources, although they are interrelated. Surface water seeps through the soil and becomes groundwater. Conversely, groundwater can also feed surface water sources. Sources of surface water pollution are generally grouped into two categories based on their origin. Point Sources Non-point Sources Point source water pollution refers to contaminants that enter a waterway from a single, identifiable source, such as a pipe or ditch. Examples of sources in this category include discharges from a sewage treatment plant, a factory, or a city storm drain. Point source water pollution re easily findable. So, people can easily control them. Non-point source pollution refers to diffuse contamination that does not originate from a single discrete source. Non-point source pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. A common example is the leaching out of nitrogen compounds from fertilized agricultural lands. Nutrient runoffs in storm water from ââ¬Å"sheet flowâ⬠over an agricultural field or a forest are also cited as examples of Non-point source pollution. 4 Surface Water Pollution : Surface water bodies are extensively used for espousal of untreated industrial wastes and this is one of the main sources of surface water pollution. Surface water pollution is caused by ââ¬â C Domestic Waste : Water pollution Of domestic is mainly caused by sewage. Sewage is defined as the waterborne waste derived from home, animal or food processing plants and includes human excreta, soaps, organic materials, different types of solids, waste food, oil detergents, paper and cloth. They are the largest group of water pollutants. Water pollution is caused by uncontrolled dumping of waste collected from villages, towns and cities into ponds, streams, lakes and rivers. C] Industrial Effluent : The discharge of industrial effluents into the water body caused water pollution. These effluents contain a wide variety of inorganic and organic substances such as oils, greases, plastics, plasticizer, metallic wastes, suspended solids, phenols, pesticides, heavy metals and acids. Major industries of the country are located on or near the coastline or riversides. Organic substances deplete the oxygen content. Inorganic substances render the water unfit for drinking and other purposes. Acids and alkalis adversely effect the growth of fish and other aquatic organisms. Oil and other greasy substances interfere with the self purification mechanism of water. Urban runoff : Urban runoff is surface runoff of rainwater created by arbitration. This runoff is one of the major sources of water pollution in many urban communities worldwide. The porous and varied terrain of natural landscapes like forests, wetlands, and grasslands trap rainwater and snowbell and allow it to slowly filter into the ground. Runoff tends to reach receiving waters gradually. In contrast, nonporous urban landscapes like roads, bridges, parking lots, and buildings donââ¬â¢t let runoff slowly percolate into the groundâ⬠¦ Arbitration also increases the variety and amount of pollutants transported to receiving waters. Sediment from development and new construction; Oil, grease, and toxic chemicals from automobiles; nutrients and pesticides from turf management and gardening; viruses and bacteria from failing septic systems; road salts; and heavy metals are examples of pollutants generated in urban areas. Sediments and solids constitute the largest volume of pollutant loads to receiving waters in urban areas. Ã'Å¡ Agricultural runoff : Water pollution can be caused by agricultural wastes such as fertilizers, pesticides, soil additives and animal wastes that are washed off from the land to the aquatic system through irrigation, rainfall and leaching. Oil pollution : There are about 15 million water crafts on navigable waters throughout the world. Their combined waste discharges are equivalent to a city with a population of 2,000,000. Thus oil pollution, an oxygen demanding Waste, is of concern not only from sensational major spills from ships and offshore drilling rigs but also from small spills and cleaning operations. Al Chemical Use : Industrial and agricultural work involves the use of many different chemicals that can run-off into water and pollute it. It can also cause health hazards to human body and many animals and fishes are dying for these chemicals. CLC Thermal Pollution : An increase in the optimum water temperature by industrial processes (steel factories, electric power houses and atomic power plants) may be called as thermal pollution. Many industries generate their own power and use water to cool their generators. This hot water is released into the system from where it was drawn, causing a warming trend of surface waters. Fifth system is poorly flushed, a permanent increase in the temperature may result. However, if the water is released into he well flushed systems, permanent increase in temperature does not occur. Many organisms are killed instantly by the hot water resulting into a high mortality. It may bring other disturbance in the ecosystem. The eggs of fish may hatch early or fail to hatch at all. It may lead to unplanned migration of aquatic animals. D Sediments : Sediment is defined as particles derived from soil or rocks that are transported by water or wind. The erosion of land surfaces and stream banks produces sediment. Sediment threatens water supplies and recreation and cause harm to plant and fish communities. Sediment can also be discharged from multiple different sources. Sources include construction sites agricultural fields, stream banks, and highly disturbed areas. D Salinity Intrusion : Saltwater intrusion is a major problem in coastal regions all over the world, as it threatens the health and possibly lives Of many people who live in these areas. It increases the salinity of groundwater and water may become unsuitable for human use. Colonization of groundwater is considered a special category of pollution that threatens groundwater resources, because mixing a small quantity of saltwater in the rainwater makes freshwater unsuitable and can result in abandonment of freshwater supply. CLC Accidental Spills of Chemicals : Accidental spills of environmentally harmful materials can happen anywhere and anytime, polluting land and water. Even echo-friendly cleaners and chemicals can harm the fish, plants and insects in our streams and harbors, if they are washed into stemware drains. 6 Ground Water Pollution : A lot of the Earthââ¬â¢s water is found underground in soil or under rock structures called aquifers. Humans often use aquifers as a means to obtain drinking water, and build wells to access it. When this water becomes polluted it is called groundwater pollution. Groundwater pollution is often caused by pesticide contamination from the soil, this can infect Our drinking water and cause huge problems. Ground water pollution caused BBC Waste disposal site : Domestic and industrial wastes are collected to dispose them in a place. There are many chemicals which are found in these wastes. The places where these waste are disposed become polluted. If the place has a leak and it lead to the nearby river, then by the leaks, the chemicals go to the river and make the river polluted. D Pesticides : Run-off from farms, skyward, and golf courses contain pesticides such as EDT that in turn contaminate the water. Leech ate from landfill sites is another major contaminating source. Its effects on the ecosystems and health are endocrine and reproductive damage in wildlife. Groundwater is susceptible to contamination, as pesticides are mobile in the soil. It is a matter of concern as these chemicals are persistent in the soil and water. L] Sewage : Untreated or inadequately treated municipal sewage is a major source of groundwater and surface water pollution in the developing countries. The organic material that s discharged with municipal waste into the watercourses uses substantial oxygen for biological degradation thereby upsetting the ecological balance of rivers and lakes. Sewage also carries microbial pathogens that are the cause of the spread of disease. C Nutrients : Domestic waste water, agricultural run- off, and industrial effluents contain phosphorus and nitrogen, fertilizer run- off, manure from livestock operations, which increase the level of nutrients in water bodies and can cause transportation in the lakes and rivers and continue on to the coastal areas. The nitrates come mainly from the fertilizer hat is added to the fields. Excessive use of fertilizers cause nitrate contamination Of groundwater, with the result that nitrate levels in drinking water is far above the safety levels recommended. Good agricultural practices can help in reducing the amount of nitrates in the soil and thereby lower its content in the water. 7 Acidification : Acidification of surface water, mainly lakes and reservoirs, is one of the major environmental impacts of transport over long distance of air pollutants such as sulfur dioxide from power plants, other heavy industry such as steel plants, and motor vehicles. This problem is more severe in the US and in parts of Europe. C] Synthetic organics : Many of the 100 DO synthetic compounds in use today are found in the aquatic environment and accumulate in the food chain. Persistent organic pollutants represent the most harmful element for the ecosystem and for human health. For example, industrial chemicals and agricultural pesticides. These chemicals can accumulate in fish and cause serious damage to human health. Where pesticides are used on a large-scale, groundwater gets contaminated and this leads to the chemical contamination of drinking water. Ã'Å¡ Arsenic Problem : Most arsenic enters water supplies either from natural deposits in the earth or from industrial and agricultural pollution. Arsenic is a natural element of the earthââ¬â¢s crust. It is used in industry and agriculture and for other purposes. It also is a byproduct of copper smelting, mining and coal burning. C Suspended Matter : Some pollutants do not dissolve in water as their molecules are too big to mix between the water molecules. This material is called particulate matter and can often be a cause of water pollution. The suspended particles eventually settle and cause thick silt at the bottom. This s harmful to marine life that lives on the floor of rivers or lakes. Biodegradable substances are often suspended in water and can cause problems by increasing the amount of anaerobic microorganisms present. Toxic chemicals suspended in water can be harmful to the development and survival of aquatic life. 8 1. 3 Common Contaminants of Water Pollution : There are some contaminants of water pollution. They are ââ¬â C Infectious Agents : Disease causing agents or pathogens, including bacteria, viruses, protozoa, parasites. These come from raw sewage and animal waste and they may be responsible for 80% of the asses in developing countries. CLC Oxygen demanding wastes : Reduce Dissolved Oxygen level in the water and affect aquatic life. Sewage, animal manure or biodegradable organic wastes are that type of waste. 0 Inorganic chemicals : Water-soluble acids, toxic compound, salt and metals are the inorganic chemicals. They make water unfit to consume and use for irrigation. Also can harm organisms and cause material corrosion. D Organic chemicals : Organic chemicals are petroleum products, oil, gasoline, plastics, pesticides, solvents, detergents. Presence of organic chemicals in water cause health kiss to humans and other organisms. Ã'Ë Plant nutrients : Nitrates, phosphates, ammonium from fertilizers are plant nutrients. Excessive algal and plant growth lower the oxygen levels when they decompose. Sediment : Sediments are bad for aquatic animals. Mud, silt, sand are the example. Sediment disrupts photosynthesis and transports large amounts of other adsorbed pollutants. Sediments are bad for Aquatic animals. D Radio-active materials : Radon, uranium, Iodine, cesium, thorium, and tritium are the radio-active materials. These materials may come either from natural or anthropogenic sources. Heat : Heat comes from cooling water for power plants other industrial plants. Heat lowers the solubility of oxygen in water and it also affects aquatic lives directly. 9 1. 4 Health Hazards Caused by Water Pollution : Virtually all types of water pollution are harmful to the health of humans and animals. Water pollution may not damage our health immediately but can be harmful after long term exposure. Different forms of pollutants affect the health of animals in different ways. Such as Heavy metals from industrial processes can accumulate in nearby lakes and rivers. These are toxic to marine life such as sis and shellfish, and subsequently to the humans who eat them. Heavy metals can slow development; result in birth defects and some are carcinogenic. Industrial waste often contains many toxic compounds that damage the health of aquatic animals and those who eat them. Some of the toxins in industrial waste may only have a mild effect whereas other can be fatal. They can cause immune suppression, reproductive failure or acute poisoning. Microbial pollutants from sewage often result in infectious diseases that infect aquatic life and terrestrial life through drinking water. Microbial water pollution is a major problem in the developing world, with diseases such as cholera and typhoid fever being the primary cause of infant mortality. Organic matter and nutrients causes an increase in aerobic algae and depletes oxygen from the water column. This causes the suffocation of fish and other aquatic organisms. Sulfate particles from acid rain can cause harm the health of marine life in the rivers and lakes it contaminates, and can result in mortality. Suspended particles in freshwater reduces the quality of drinking water for humans and the aquatic environment for marine life. Suspended particles can often reduce the amount of sunlight penetrating the water, disrupting the growth of photosynthetic plants and micro-organisms. There are some water borne diseases of human which caused by drinking or using polluted water. They are given pillowcase Bacterial infections Viral infections Protozoan infections Hellishness infection Diseases Typhoid, cholera, Paratyphoid fever, Dysentery Infectious Hepatitis (jaundice), Poliomyelitis Amoebic dysentery Roundworm, Hookworm, threadbare 10 2. 0 Global Warming 2. What is Global Warming : Global warming is defined s a natural or human induced increase in the average global temperature of the atmosphere near the Earthââ¬â¢s surface. The temperature at or near the surface of the Earth is determined by four main factors : ; ; ; ; The amount of sunlight Earth receives. The amount of sunlight Earth reflects. Retention of heat by the atmosphere. Evaporation and condensation of water vapor. In the last 100 years, Earthââ¬â¢s average surface temperature increased by about 0. 8 co (1. 4 OF). Two thirds of the increase occurred over the last three decades. Warming of the climate system is unequivocal. Scientists are more Han 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities. These findings are recognized by the national science academies of all the major industrialized countries. 11 2. 2 Causes of Global Warming : Scientists have spent decades figuring out what is causing global warming. Theyââ¬â¢ve looked at the natural cycles and events that are known to influence climate. But the amount and pattern of warming thatââ¬â¢s been measured canââ¬â¢t be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases emitted by humans. There are many natural causes of global warming. But they do not warm much the planet. The most serious type of warm is anthropogenic which is created by humans. One of the first things scientists learned is that there are several greenhouse gases responsible for warming and humans emit them in a variety of ways. The causes of global warming are given below -? Greenhouse Gases : Sunlight that reaches Earth warms both the atmosphere and the surface. Earthââ¬â¢s surface and atmospheric system then irradiate heat as infrared radiation. Certain gases in Earthââ¬â¢s atmosphere absorb and re-emit this radiation. Some of it returns to the Earth ;s surface, making Earth warmer than it otherwise would be. In trapping heat, the gases act a little like the panes of glass in a greenhouse (although the process by which the heat is trapped is not the same as in a greenhouse), accordingly, the effect is called the greenhouse effect, and the gases which include Water vapor, carbon dioxide, methane, and chlorofluorocarbons (CIFS) are called greenhouse gases. Extra Carbon Dioxide Release : Human are releasing Carbon dioxide in the environment by burning fossil fuels, burning trees, driving cars and from the industry. This excessive carbon dioxide is not absorbed by the environment. This makes our planet warmer and the result is global warming. CLC Methane Gas from animals, agriculture, Arctic Sea beds: Methane is another extremely potent greenhouse gas, ranking right behind CO. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in rice paddies, methane is produced. The process also takes place in the intestines of herbivorous animals and with the increase in the amount of concentrated livestock production, the levels of methane released into the atmosphere is increasing. Another source of methane is methane celebrate, a compound containing large amounts of methane trapped in the crystal structure of ice. As methane escapes from the Arctic sea beds, the rate of global warming will increase significantly. 12 0 Solar Variation : Variations in solar output have been the cause of past climate changes. The effect Of changes in solar forcing in recent decades is uncertain but small. Some studies showing a slight cooling effect while others studies suggest a slight warming effect. C] Nitrogen Oxides from Farming : Primary component of the green revolution has been the development of iatrogenic fertilizers that dramatically accelerate the growth and productivity of plants in the field. Plants fix or capture, nitrogen on their own as well but green revolution technologies have become so popular that humans are now adding more nitrogen to the earth than all of the plants in the world combined. Nitrogen oxides have 300 times more heat-trapping capacity per unit of volume than does carbon dioxide and we release them every time we apply fertilizer to soil. A recent United Nations Food and Agriculture Organization study found that modern farming is contributing more to global arming than all of the transportation sector combined. This is due partly to the fuel burned in modern farming, but more significantly, to the release of methane and nitrogen oxides. C] Chlorofluorocarbon (CUFF) Gas : Chlorofluorocarbons (CUFF), is used in refrigeration, also powerful greenhouse gas. These gas occur in lower concentrations in the atmosphere, but because they are so much more potent than carbon dioxide, in some cases hundreds of times more potent per unit of volume, they contribute to global warming as well. CLC Deforestation Deforestation increases the severity of global arming as well. Carbon dioxide is released from the human conversion of forests and grasslands into farmland and cities. All living plants store carbon. When those plants die and decay, carbon dioxide is released back into the atmosphere. As forests and grasslands are cleared for human use, enormous amounts of stored carbon enter the atmosphere. Burning Gasoline for transportation : Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions in the U. S. With our population growing at an alarming rate, the demand for more cars and nonuser goods means that we are increasing the use of fossil fuels for transportation and manufacturing.
