Not Enough Fish in the Sea

Overfishing means catching fish faster than they can reproduce. Overfishing pushes the fish population lower and lower, until fish are so few that fishermen can’t make a living any more. Many fisheries have already collapsed.

In the second half of the 20th century, ocean fishermen increased their catch 400% by doubling the number of boats and using more effective fishing gear. In 1989, the world’s catch leveled off at just over 82 million metric tons of fish per year, which is all the ocean can produce.

Overfishing affects the marine ecosystems in which species are embedded. Scientists warn that this will result in profound changes in our oceans, perhaps changing them forever. (Source: Greenpeace, Monterey Bay Aquarium.)

The graphic below illustrates the current status (as of 2001) of fish stocks. For a graphic illustrating the effects of overfishing, see here. And for one showing the challenge of rebuilding depleted fish stocks, see here.

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
