Seasonal Animal Deaths Animals dying are a very important matter when it comes to pollution and hunting. Killing animals is wrong and we should do something about it. This page is about the causes of animal deaths. Lots of animals are dying from pollution. All types of environmental pollution have an impact on animals health. Even smaller levels of pollution create discomfort for many animals while bigger levels of pollution lead to diseases and deaths. Air pollution is particularly dangerous to animals when it is formed into acid rain. Acid rain kills fish in lakes, rivers, and streams by increasing the acidity of the water. Water pollution is very hazardous also. When water is polluted with different chemicals, it can cause a drop of population in some species (such as the frog). When water is polluted with nutrients, it can lead to a huge growth of toxic algae, which when eaten by other animals, may cause diseases and death. Did you know that Bald Eagles, Peregrine Falcons, and Brown Pelicans became extinct due to synthetic chemical. This devastated the reproductive failure in these species. Littering is hazardous to animals because of the toxic substances in the trash\garbage. That's why there are signs saying "No Littering." As a matter of fact, plenty of animals die due to being hunted by humans also. Animals also eat other animals. They do this as a way ofsurvival. Animals have no alternative.
