Pollution is killing and harming wildlife in the united states and all around the world. Oil spills are very bad and have huge affects on wildlife, toxic metals like lead kill many animals each year, pesticides are thought to be good for crops but have bad affects on wildlife.

Another way of agriculture hurting wildlife is irrigation which can leach toxic substances from the soil. When these substances are leached from the soil they are exposed to wildlife.

The use of lead in gasoline released a lot of lead into the air from the vehicle exhaust and contaminated water and land around roadways. The wildlife living near the road showed to have an increased amount of lead in their system. The effects of lead on the neurological development of humans is the primary reason that the use of leaded gasoline has been curtailed dramatically in the last 20 years(Davis).
