The impact of oil on the environment is...
When a oil spill occurs the fish get contaminated and if we eat them we get sick(humankind impact/environment impact). The animals in the sea are not harmed because the oil just sits on top of the water. It is only if the animals go to the surface, they will get oil all over them and possibly die. If they put an oil rig in a lake the water will fill up the hole where the oil came out of and then the fish will die because they have no water.
