H2O Pollution

          Water pollution is the effect that humans leave on water bodies, pollution is usually with waste products. This includes chemicals in water, bacteria in water, and other stuff such as acidity or conductivity. Water pollutants also include herbicides, bacteria (sometimes from food processing waste), tree and plant debris from things such as logging, fuels, detergents, chemical waste, fertilizers and many more.

          Usually, water pollution begins in streams and rivers which make their way to an ocean. In these streams and rivers, small algae called plankton are 'infected' by the polluted water. This also affects the food chain and, as such, plankton aren't the only wildlife affected. For example, a small fish might eat the plankton. Then as the food chain continues and that fish is eaten by a larger one, perhaps going up to a bear or bird, the larger creatures are affected by the pollutants in the smaller ones they consumed.
