How does poluttion affects animals?

Many people ignore the fact that our planet is now polluted more than ever before, and that many animals are dying because of it.
 Air pollution is particularly dangerous to animals when in form of the acid rain. Acid rains kills fish in lakes and streams by increasing the acidity of water. Water polluted with different chemicals can cause decline of population in some species (such as frog), while on the other hand water polluted with nutrients can lead to huge growth of toxic algae which when eaten by other animals may cause serious diseases and death to these animals. Noise pollution is also becoming huge problem for many animals. Because of the increased ship traffic and offshore oil drilling noise pollution has started affecting very large number of marine animals. Whales and dolphins are among animals most affected by noise pollution. Littering can also lead to death of many animals because of toxic substances in trash that once eaten by animals often lead to their deaths. By reducing all forms of environmental pollution on our planet we could save millions of animals but sadly world is currently not doing enough, and pollution issue is therefore constantly growing in size. Add to this climate change and deforestation and you'll soon realize why so many animals are finding it very hard to survive.
