Environmental Impacts

  • affects surface resources and a wide range of subsurface organisms
  • all organisms that are affected are connected in a complex food web that affects humans
  • causes physical damage that impacts wildlife and their habitats
  • the toxicity of oil can poison exposed organisms
  • there are short term and long term effects
  • some organisms may be seriously injured or killed after contact with an oil spill
  • longer lasting effects include freshwater organisms being slowly smothered by oil as is carried by a current
  • marine oil spills do not only affect fish, but also mammal and bird species

What can we do?

  • Sometimes leaving the oil to break down by natural means is the best option
  • However, thicker, more harmful oils are contained and collected with specialized equipment.
  • Detergents are often used to break up the oil and to clean up animals from the ecosystem.

  • New laws are put into place every time an oil spill happens to prevent a similar crisis from happening in the future.
  • The main cause for oil spillage is our dependence on fossil fuels.

A new, renewable energy source is ideal for prevention.
