CHAPTER I
THE PROBLEM AND ITS BACKGROUND
INTRODUCTION Water they say is life, and indeed they were right. With about 70% of the earth’s cover being water, it undeniably becomes one of our greatest resources. Water pollution is an appalling problem, powerful enough to lead the world on a path of destruction. Water is an easy solvent, enabling most pollutants to dissolve in it easily and contaminate it. The most basic effect of water pollution is directly suffered by the organisms and vegetation that survive in water, including amphibians. On a human level, several people die each day due to consumption of polluted and infected water. Oil contamination of water pose a huge concern as large

It can be used to clean up environmental problems like an oil spill or contaminated water. The use of living organisms (primarily microorganisms and plants) is emerging as one of the most useful alternative technologies for removing contaminants from the environment, restoring contaminated sites, and preventing further pollution. The natural biological processes can be explored to remediate nutrient-rich water by converting nutrients in to forms that can be more easily removed. These microbes consume the contaminants, converting them into small amounts of water and harmless gases like carbon
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
Finally, write a concluding paragraph for the essay, without plagiarizing. Bioremediation, or the use of biological remedies for pollution reduction, is being tested as a potential solution to certain environmental catastrophes. Bioremediation has been used to treat sewage for many decades. Recently, it has been investigated as a treatment for refractory chemical wastes.
“Water for Life”, an article by Sandra Postel, appeared in Frontiers in Ecology and the Environment in March of 2009. Why is it that with all the efforts going into solving the worlds water preservation problem we haven’t found a way to fix it? Postels’ response is simply that society views water in a utilitarian fashion and “modern society’s disconnection from natures web of life” and from waters role as the “basis of that life”. Sandra Postel is a good source for this opinion because she is the director of the Global Water policy project; She is also the Freshwater Fellow of the National Geography Society, serving as its Freshwater Initiative lead water expert. This article was possibly a response to The Water Conservation Act of 2009 that was in senate in March.
Wastes deposited by the animals can introduce nutrients and disease-causing organisms into the water, posing problems for aquatic organisms as well as human populations that use the water.” Another way that humans can negatively impact the water quality is by fertilizers and pesticides being put into the water. When this happens it can make the nitrogen and phosphorus levels increase which can be lethal to the organisms in
Of course, it may not do much harm, but yet, water should purified and clean. Especially lakes. But water contamination can heavily affect those that aren’t really hooked up to a main water line specifically for drinking and other personal uses. Also for those that still live in isolated areas and have to go and haul their own water.
The B. Vulgaris samples were approximately 1cm3. They were kept the same size to ensure accurate results. A control test was conducted in distilled water to obtain a result to compare. The ethanol treatments were 40% and 70%. To prepare the solutions a 70% ethanol solution was used to make 40%.
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
Stop Taking Clean Water for Granted Can you stop for a moment and think what would happen if we didn’t have water; clean water? It seems impossible, as we use water to drink, cook, clean, grow things, and for everything else in life. Unfortunately, because of the easy access to one of the most plentiful, and most valuable resources in the world, some people take water for granted. In contrast, other poor people live in places where the only easy way to get water is from a dirty irrigation ditch. Or their only source of water is backyard faucet shared by several homes.
Marine pollution such as presence of organic matter in the ocean can result in the condition known as hypoxia or oxygen depletion and this can have adverse effect on the marine life including plant and animals and fish. Death of these fish can result in loss of millions of US dollars that are generate from the fishing industry. Marine pollution can also result in presence of foul smell resulting from the decomposing sewage being directed to the ocean and this has the effects to hinder recreational activities taking place in the sea as well as cause discomfort and breathing problem to the surrounding population (Laura, 11).marine pollution can also result in danger to human health. The human swimmers and water sport lovers can become endangered by swimming in the polluted marine waters (Laura,
Water can no longer continue to stay unprotected, it is simply too important. Today most countries have laws aimed at safeguarding water quality and controlling water abstractions (Groenfeldt, 2013). In 2010, a new human right to ‘safe water and sanitation’ was recognized by the United Nations and implemented effective immediately. Water not only feeds the human body, but also the earth. Without water, nothing can grow.
Water pollution is a serious issue as not only is water the most precious natural resource, but all sources of water support life that is very necessary for the survival of the planet. Water pollution destroys life and ecology and such damage is irreparable. Those who are still not serious about water pollution must also remember that the pollutants present in water not only destroy the life in the rivers and oceans, but also affect our food chain. Many people have the wrong notion that since they are not disposing the pollutants in the water they are not to blame. These people forget that 70% of the earth is covered by water, and any activity on the land can wash to the seas and oceans.
Environmental issues began to be discussed and debated only towards the end of the 20th century. Since then significant amount of literature has been penned down raising awareness about issues of pollution, deforestation, animal rights and several others however it has failed to result in major changes, ideas or even actions to save the environment. Several species of animals have become extinct; pollution level is at an all-time high, global warming is leading to severe climate changes all across the globe but these problems do not seem to alarm the decision makers. Leydier & Martin (2013) also states that, “despite the increasing expression of concern in political and media debates about issues such as climate change, pollution and threats
Water is one of the most important and vital substance on earth. All life forms on earth require water to survive. If there will be no water there would be no life on earth. Aside from drinking water to survive, people have many other uses for water.
Water is the most important component found on the surface of the earth because it is source of life for living creatures. However, water pollution has become a global concern. Water pollution can have several forms from diverse sources. It is expected that there will be a lack of clean water in next few decades due to pollution. Nile river water in Egypt is the focus of attention of many studies due to many reasons.
Introduction By the year 2025, the Philippines is believed to be brought to a water crisis if no new sources of water are developed or found to meet the growing demand of the citizens. (Sapnu, R., Balabo, D., & Cervantes, D., 2007) "There is a Japan International Cooperation Agency study that says that if we will not conserve water, there may be some problems. But of course we can always start conserving now and look for other sources," Lopez (2013) said. Studies have shown how water conservation and appropriate water utilization are significant as early as today.
