I chose water pollution because it seems like a major issue right now. There are many ideas of how water pollution is caused, but we need to worry about how to solve it. Water pollution has been suggested to be the leading worldwide cause of death and disease, and that it causes more than 14,000 deaths per day. If water pollution isn't fixed, it will ruin our drinking water supply.

Water pollution has many causes including sewage and fertilizers containing nutrients such as nitrates and phosphates. Pollution is also caused when silt and other suspended solids, like oil, wash off plow fields, construction and logging sites, urban areas, and waste-filled river bank when it rains. Water pollution exists in 3 forms of petroleum, radioactive substances, and heat.

All water pollution effects organisms and plants that live in these bodies of water and in almost all cases, the effect is damaging either to individual species and populations, but also to the natural biological community. Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of death and disease, and that it accounts for the deaths of more than 14000 people daily.

The effects of water pollution are varied and depend on what chemicals are dumped and in what location. Many bodies of water are polluted near urban areas. This is because both garbage dumped by individuals and chemicals dumped legally or illegally by industries. Dead fish, dolphins, birds, and many other animals wind up on beaches, killed by harmful pollutants. Many areas are being effected by careless pollution, and it is coming back to hurt humans.

Water pollution is a major problem and we need to fix it. If we don't, we will run out of water that we need. People don't realize what this world is turning into. We need to change our ways.

Water pollution is one of the most serious environmental problems. It occurs when water is contaminated by such substances as human and animal wastes, toxic industrial chemicals, agricultural residues, oil and heat. Most of our water bodies— rivers, lakes, seas, oceans, estuaries and underground water sources (i.e., tubwells, bore wells) are gradually becoming polluted. In the course "Covered so far, you have seen how deforestation, urbanization, intensive agriculture and industrialization have caused pollution of water bodies.
