Why is oil toxic to wildlife?
Impacts to Wildlife and Habitat
Floating oil can contaminate plankton, which includes algae, fish eggs, and the larvae of various invertebrates. Fish feeding on these organisms can subsequently become contaminated through ingestion of contaminated prey or by direct toxic effects of oil.
How does oil harm nature?
Fossil fuel development can also leak toxic substances into the soil and drinking water sources, causing cancer, birth defects and liver damage. Black, Brown, Indigenous and low-income communities are disproportionately impacted since these groups tend to live in neighborhoods with more pollution.
How does oil harm marine animals?
Birds, Fish, and Sea Mammals

Why is oil so harmful to birds?
When oil sticks to a bird’s feathers, it causes them to mat and separate, impairing waterproofing and exposing the animal’s sensitive skin to extremes in temperature. This can result in hypothermia, meaning the bird becomes cold, or hyperthermia, which results in overheating.
Why is oil so harmful?
