The document discusses various types of water pollution like littering, dumping, and oil spills. It focuses on oil spills and their effects on marine life such as birds, sea mammals, fish, and plants. An experiment is described where a feather is placed in clean water, soapy water, and oily water to observe the effects of oil on feathers. The results show that in oily water, the feather clumps tightly together, preventing birds from flying or keeping warm if their feathers became oiled. Oil spills can damage gills and prevent oxygen intake in fish. The document encourages learning about how to protect the environment.
