How does pollution affect animals?
We all know that pollution is a big problem for people.
But pollution is a problem for animals as well.
Pollution can cause animals to get sick or die.
Or cause their eggs to fail to hatch.
Types of Pollution
Acid Rain
Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides from power
plants, cars and factories.
These emissions bond with the water vapor in clouds and cause the resulting rainfall to be acidic.
Acid rain can harm trees, kill fish and cause the birds that prey on fish to lose their source of food.
Water Pollution
Water pollution is the contamination of lakes, rivers, oceans, and groundwater
by pesticides, fertilizers, or garbage.
Pesticides used to control lawn and crop insects can enter a pond during heavy rains
and cause a fish kill.
Fertilizer runoff can cause an unnaturally heavy algae bloom. Too much algae can deplete
oxygen in the water and cause fish to die.
Once let loose into the environment, plastic bags can cause considerable harm, blocking drains and suffocating wildlife mistaking the
bag for food.
Oil spills sicken and kill birds and marine mammals. Oil is absorbed by feathers and
fur. Animals are unable to remove it.
