Oceans 101
We all have the ability to affect our oceans, for better or for worse, no matter where we live.
Oceans 101 is an introduction to what you need to know about our oceans, the threats they face, and what you can do to help protect them.
More than 70 percent of the globe is covered by the ocean and half the world's human population lives within minutes of the coastline. Rich with resources and potential, our oceans have long been thought of as both infinite and indestructible. But they are not. Overfishing, climate change, pollution, acidification, dead zones, and more have put the world's ocean and marine life at great risk. Increasingly, we face the real possibility of seas without edible fish; an acidic, plastic-filled ocean in which nothing can survive except jellyfish; rising sea levels and mass extinction of fish and mammals. Yet if we take action now, this grim future can be avoided.
