ExxonMobil Says Goodbye To Russian Arctic Oil Well (Part 1)

You may well ask why PlanetSave, a blog usually dedicated to positive developments and actions to save the earth, is reporting news about ExxonMobil and a Russian arctic oil well. The oil discovery appears to have nothing to do with solar or wind or most of our usual topics—we’re talking fossil fuels here, which have caused much […]

What Exactly Lies In The Deep-Sea? New Report Examines The Question

With the deep-sea more-and-more becoming an object of interest for those in the various mining and fossil fuel extraction industries that our civilization depends on, the question of what exactly is being threatened by said interest has come up. To put it another way, what invaluable services does the deep sea provide for free that […]

Shape-Shifters, Vampires, And Chimeras Under The Sea (video)

Where did that octopus emerge from? (Gallo TED talk) Having recently visited Fabien Cousteau’s Mission 31 under the sea and a water creature from long ago (Lyrarapax unguispinus), we thought it might interest you to revisit what’s hiding deep in the oceans today. For this, we turn to a classic video from oceanographer David Gallo: “Underwater […]

Maine’s Kelp Forest Under Threat!

The Gulf of Maine’s best kept secret is under threat of being clear-cut. Cashes Ledge is an underwater mountain range which contains the largest and deepest kelp forest on the Atlantic Seaboard. It is an area of upwelling that brings nutrients to the surface causing the kelp forest to blossom and plankton to bloom. It […]

Watch Cousteau Ocean Climate Study LIVE in June! (videos)

Fabien Cousteau, ocean explorer and grandson of famed Jacques-Yves Cousteau, began a historic subsea mission on Sunday. He’s studying ocean impacts of climate change (especially acidification, which occurs as the sea absorbs atmospheric carbon dioxide), effects of plastic and other pollution on marine life, and overfishing of marine resources, which diminishes the ocean’s biodiversity. You […]

Lancetfish — Facts, Images, And Warnings

The Lancetfish — perhaps you’ve never heard of it? Perhaps you should have? Perhaps you’ve seen the recent viral images of a lancet fish that washed up on the shores of North Carolina? And are wondering if they’re real or not? Have you ever seen anything like THAT before? Lots of important questions. 🙂 Perhaps […]

Future Ice Melt Patterns In Antarctica

One of the main impacts of climate change is sea level rise, brought about through melting of the world’s ice sheets and glaciers, as well as through thermal expansion of the oceans. The vast majority of world’s fresh water is locked up in the massive ice sheets covering Antarctica and Greenland. Of the two, Antarctica […]
