Oil spills are a very serious form of pollution. They severely affect marine biodiversity and coastal ecosystems. The table show
s methods that can be used to control oil spills.
A scientist wants to design a solution to control an oil spill. This solution should decrease the impact of the oil spill on the local biodiversity of the ecosystem. The solution should also be quick and effective but have minimal negative effects on the environment. Which of the following solutions would be best for the scientist to choose?
A. allowing natural processes to occur without any human intervention
B. using mechanical methods to collect the oil in one part of the ecosystem
C. using chemical methods to break the oil into smaller droplets
D. using bioremediation to speed up existing, natural oil degradation
Hellpppp!
