Cumulative Impacts of Human Activity on the Oceans

Have you ever wondered what the impact is of human activity on the world’s oceans?

In short, a lot.

This animation shows the cumulative impacts of human activity on the oceans. Green represents areas with less impact, and red represents areas that experience much greater impact.

A study by Dr. Kenneth Casey in Feb 2008 , with NOAA’s National Oceanographic Data Center, shows that 40% of the world’s oceans are heavily affected by human activities like overfishing and pollution. The marine ecosystems most threatened by human activities are coral reefs.

The ocean impacts the lives of everyone on Earth, even those who do not live on or near the coast, and humans affect the ocean in a variety of ways. Individual and collective action is necessary to wisely manage ocean resources for all.
