Human Impacts on Marine Life
Evidence suggests that overfishing, oil spills, pollution, and climate change are just a few examples of how human actions are changing the ocean's environment beyond what it naturally is. Numerous scientific investigations have found that there are many locations where marine species are diminishing. This has an effect on marine ecosystems and may have unfavorable effects on biodiversity. Before pushing the oceans to their breaking point, we must control the risks.
