Effects of Water Pollutions Water is important for the existence of life on earth. All organisms require it and aquatic plants and animals live their life in water. Water pollution occurs when you have toxins and pathogens present in water in dangerous amounts than permissible. One of the worst forms of pollution in the ecosystem is water pollution. When you hold a glass of water it may appear to be clean and clear. But the fact is there are millions of microscopic pollutants suspended in it. Water is a very vibrant system and any change would cause a greater damage to the marine biology at large. The effects of water system are far reaching and affect human beings, plants, and animals directly or indirectly. Water pollution affects lakes, oceans, rivers, bays and drinking water making it a global crisis. This condition also leads to the eruption of various diseases and most of them being transmittable and fatal. Water is known be polluted when there are chemicals, contaminants or pathogens detected that are harmful to living things. Given below are the effects of water pollution that can have detrimental effects to the existence of life on earth.

Harmful Effects of Water Pollution

· One of the major effects of water pollution is the damage to the food chain. When harmful toxins are present in water they are transferred to higher level organisms through the food chain. These toxins are passed on to humans and animals as well. Dangerous pollutants such as lead and cadmium are eaten by tiny animals and these are then consumed by fishes and larger sea animals. This food chain is distributed to the higher levels.
· Heavy metals like lead, mercury, iron, cadmium, aluminum, and magnesium are present in water sources. If these metals are present in the sediment, these reach the food chain through plants and aquatic animals. This causes heavy metal poisoning in the water.

· Polluted water is a hot bed for diseases. Microbial
