A split-panel visual showing the main threats to the ocean. From left to right: tangled fishing nets (overfishing), a polar bear on melting ice (climate change), a plastic bag floating underwater (pollution), and bleached coral (habitat loss). Bold text at the bottom reads: “THE OCEAN IS IN CRISIS.” UN Environment Programme logo appears in the top right.

The ocean shields coasts, sustains biodiversity, and feeds billions.

While leaders pledged to protect 30% of it by 2030, only 8.4% is protected today.

UN urges countries to ratify landmark High Seas Treaty UN Secretary General Antonio Guterres urged world leaders to ratify the treaty, warning that fishing, plastic pollution and rising sea temperatures were destroying ocean ecosystems.

The program is now under threat. www.pressdemocrat.com/article/news...

Illustration of Rachel Carson with cool things swirling around her - jellyfish, birds, turtles. She is holding binoculars and a water sample and a field notebook. Quote below her reads: “The human race is challenged more than ever before to demonstrate our mastery, not over nature but of ourselves.”

Received a thank you card after a recent event for @ateverydepth.bsky.social and it’s just so perfect! Starting monday with a beautiful illustration by @rachelignotofsky.bsky.social and wise words by Rachel Carson:

President Biden Permanently Protects Vulnerable Areas of the Ocean from Oil and Gas Drilling The president used a federal law to ban future oil and gas drilling in parts of the Atlantic, Pacific, Alaska, and the Gulf of Mexico.

In his final weeks in office, President Biden protected 625 million acres of vulnerable areas of the ocean from oil and gas drilling — in a way that incoming president-elect Donald Trump can't easily undo.

In the announcement, the Biden administration acknowledged that one of the motivations for this action was lessons learned from the Deepwater Horizon oil spill - something we discuss extensively in @ateverydepth.bsky.social.

The #penguinpicoftheday #PPOTD is from last year right around this time when I was at Atka Bay with the emperor penguins there. This colony moved substantially in the couple of weeks I was there.
