Causes of endangerment:pollution



well there are many different types of pollution such as, Air pollution, water pollution, soil pollution. radioactive pollution, and many more! so lets take a look of how some of these types of pollution causes animals to become in dangered.
  • air pollution: Air pollution is caused when air gets filled with too much gases, particulate matter, and droplets of liquid. In cities, the air gets polluted by exhaust fumes of vehicles, along with the pollutants given off by construction work and industry. so what does it do to animals? well many animals are actually dying and it leads to diseases too. Air pollution is particularly dangerous to animals when in form of the acid rain.

  • water pollution: Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives in it. When humans drink polluted water it often has serious effects on their health. Water pollution can also make water unsuited for the desired use.Water pollution has extremely negative impact on many animals. Water polluted with different chemicals can cause decline of population in some species, 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.


  • radioactive pollution:The radioactive pollution is defined as the physical pollution of air, water and the other radioactive materials. animals can withstand higher doses of radiation than humans, which partially accounts for their success in repopulating the area. Even so, animals are affected by radiation, and some species, particularly birds, show unusually high cancer rates. Whether they'll adapt over time remains to be seen.
