The ocean is full of “hope zones” that need to be protected

Due to its vast extent, the ocean is able to capture at least 25% of the carbon dioxide that humans emit into the atmosphere.

But such impressive power cannot be expected without protecting the sea itself, experts who participated in CNN’s Call to Earth Day on Thursday said. Scientists suggest avoiding fishing and mining in large areas of the ocean, restoring ecosystems such as coral reefs, and preventing pollution from entering the water.

If a warming ocean can do its part to save the planet in its current state, a healthy ocean could have an even bigger impact, experts say.

Secrets of the ocean

The ocean is full of hope. Just ask the Queen of the Deep herself, Sylvia Earle.

The 87-year-old oceanographer has spent much of his life exploring the ocean and still holds the world record for the deepest untethered walk on the sea floor.

“Every time I get in the water, I see things I’ve never seen before,” he said.

Its Mission Blue program, which supports ocean research and restoration, has identified more than 140 marine areas around the world that are critical to ocean recovery. Designated as Hope Spots, these special places are cared for by local communities and organizations.

Wild kingdom

Gray nurse sharks may look menacing with their ragged, needle-like teeth, but a 16-year-old marine conservationist from Port Macquarie, Australia, would beg to differ.

“They are so tame and so curious,” said Shalise Leesfield, who works to protect critically endangered species. “They are like the Labradors of the sea.”

Slug sharks, which feed on wrasse, urchins and other bottom dwellers, still inhabit Fish Rock, a colorful coral-filled underwater cave off the coast of the South West Rocks, 40 miles (64 kilometers) offshore from their home. . Thanks to Leesfield, the cave ecosystem has been named the Hope Spot.

He wants to establish a sanctuary area where sharks that are largely harmless to humans can continue to reproduce and survive.

Solar update

The sun appears smiling in a new image taken by NASA's Solar Dynamics Observatory.

The sun is coming, and I’m glad to see you.

NASA’s Solar Dynamics Observatory captured what appears to be a smile on our star from the vantage point of space. Some social media users thought it resembled the Stay Puft Marshmallow Mana from “Ghostbusters,” but the dark patches are called coronal holes.
These holes in the Sun’s surface can release powerful streams of solar wind, or charged particles, that can reach Earth. And it’s something we’ll see more of as solar activity increases before the solar maximum in 2025.
Meanwhile, astronomers have spotted a ‘planet killer’ asteroid hidden within the sun’s glare, which has the potential to cross Earth’s path in the future. The space rock is the most dangerous asteroid discovered in the last eight years.

“Compostable plastic” is not as planet-friendly as it sounds.

Bags, cups, plates and cutlery touted as biodegradable alternatives to harmful single-use plastic products are not regulated, and a new study has found that 60% of products labeled as compostable do not fully break down.

Instead, keep reusable containers on hand, such as mugs or bottles for on-the-go drinks. And if you see two versions of the same product with different packaging, choose cardboard instead of plastic.

Two casts of an ancient marine reptile fossil were made with a drawing from 1819 (above).

The curious story of an ancient creature was just beginning in 1818 when fossil collector Mary Anning discovered an unusual specimen in southwest England.

He discovered the first complete skeleton of a prehistoric marine reptile called an ichthyosaur, and his discovery helped spawn a young field called paleontology. But the fossil was destroyed in a World War II bombing.

A chance discovery by two researchers revealed two unknown plaster casts of the skeleton stored in museum vaults, one in the United States and the other in Germany.

The plays, which preserve the precious details of a precious fossil once lost forever, date back two decades before the word dinosaur was used.
