Along the coasts of heavily populated communities, scientists have found more and more dead zones – areas where depleted oxygen levels cannot support marine life. 146 dead zones were found in the world’s oceans, caused by high levels of chemicals in the waters. North America’s Gulf Coast has a high concentration of dead zones, which causes fish to become unable to reproduce. You might think that if you live on land, you won’t be affected by oceanic dead zones but if you eat seafood, seaweed, or care about air quality, you won’t want to ignore this issue.
The good news is that dead zones can be reversed, though it is difficult. The Black Sea dead zone disappeared in 1991 and 2001 due to the discontinued use of fertilizers. To find out more about how you can help with dead zone cleanups, visit Oceana.org.
