The Gulf of Mexico dead zone is set to bust all its own records. Forecasts suggest this super-duper-unproductive ocean zone will reach 8,800 square miles this summer. That’s the size of New Jersey.

Last year it reached 7,903 square miles. The earlier record was 8,481 square miles in 2002.

Notice a trend?

Notice the Bizarre-New-Age-of-Abysmal-Record-Everythings we’ve entered?

For those of you who’ve been asleep during the Bush-van-Winkle years, here’s the primer. A dead zone forms when fertilizers wash from farms via rivers to fertilize the sea.

There are other reasons too. Including whatever nutrients you add to your lawn. Don’t even get me started on golf courses.

So this year’s climate-change-induced record floods on the Mississippi River do a lot more damage than to Midwestern croplands.

That’s because the ocean doesn’t like a lot of fertilizer. It makes too many plants grow. Those plants die and feed too many decomposers who use up all the oxygen in the water. Everything suffocates.

Dead zone. Coming soon to a seashore near you.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
