Every year, thousands of sea turtles die from their dangerous migrations in the high seas. Fraught with jeopardy, some must swim as far as 1,250 miles to reach their nesting grounds, but many never complete the journey.

Deep sea mining, overfishing, entangled fishing gear—these are just a few of the perils they face on their treacherous swim. Abuses like these regularly go unchecked in the high seas that cover nearly half of our planet. The high seas are a no-man’s land—vast open areas of ocean beyond any national territory—with few regulations and even fewer consequences. We simply cannot save our ocean unless we protect marine life in the high seas.

There’s never been a more urgent time to safeguard our ocean and the diverse marine life in the high seas. That’s why a new, legally binding treaty to protect marine biological diversity is so critically needed.

Now’s the time for urgent action. To create the biggest public outcry possible, we’re joining together with more than 25 like-minded organizations to show the collective strength of our Voice for the Planet and create the biggest collective demand for nature we have yet seen.

Pledge to stand with The Nature Conservancy to call on global leaders to back a strong treaty to protect the high seas. If we don’t take action now, the costs will likely be catastrophic.
