Human Impacts on Marine Life

November 15, 2017 | 02:22

Evidence shows that human activities, including overfishing, oil spills, pollution, and climate change are altering ocean environment beyond their natural state over the last few decades. According to numerous scientific studies, marine species are declining in many places, which impacts on the marine ecosystems and may lead to undesirable consequences for the biodiversity. We need to manage the risks before pushing oceans to their limit.
