Could Seaweed Be Key to More Recyclable Packaging?

By Sarah Lozanova

As consumer demand for more sustainable packaging increases, DS Smith is researching the use of seaweed in paper and packaging products. In particular, the British multinational packaging company is exploring seaweed as an alternative fiber to wood. If successful, it would be the first company in the packaging industry to take this approach. The company is also examining the potential of seaweed as a barrier coating, potentially replacing petroleum-based products.


Seaweed Farming: Could This Carbon-Negative Crop Help Restore Our Oceans?

China has been cultivating seaweed for about 1,700 years. Coastal populations harvested a wide variety of the algae first as a source of food and animal feed, but later for industrial purposes and nutritional supplements as the practice became more widespread.


A critical ocean system may be heading for collapse due to climate change, study finds

By Sarah Kaplan Photo: Salwan Georges/The Washington Post

Human-caused warming has led to an “almost complete loss of stability” in the system that drives Atlantic Ocean currents, a new study has found — raising the worrying prospect that this critical aquatic “conveyor belt” could be close to collapse.


Deep sea trawling unleashes carbon from the ocean floor

When a whale dies, it sinks to the bottom of the ocean. As it decomposes, much of the carbon that makes up its body stays on the sea floor. The same thing happens when other ocean creatures die, creating a carbon-rich sediment that builds over millennia.


Far from Basic: Action Needed to Fight Ocean Acidification

President Biden’s first year in office is gearing up to be an important year for climate action in the United States and globally—this includes ocean climate action. The benefit of taking comprehensive climate action isn’t just curtailing carbon dioxide emissions released into the atmosphere. Climate action also prevents excess carbon dioxide from dissolving in our ocean. This process, known as ocean acidification, needs to continue to be a part of our conversations about how to act on climate.


Policymakers Have Last Chance to Save Coral Reefs From Global Collapse, Warn Scientists

By Elizabeth Waddington Photo: Brett Monroe Garner , Getty Images

Scientists had a dire warning at the International Coral Reef Symposium: this decade is a make or break for coral reefs. According to the paper presented at the symposium, this decade is the last chance for policymakers on all tiers to prevent coral reefs “from heading towards world-wide collapse.”1


Collaborative Ocean-based Solutions to Climate Change — Together We Can

By Rob Moir

o meet the ravages of climate change, Congress has introduced the Ocean Based Climate Solutions Act (HR.8632). The ocean covers nearly three-quarters of the planet. Nothing has more of an impact on the climate than does the ocean. About one out of every four carbon dioxide molecules emitted into the atmosphere are drawn down into the ocean. Sea water along our shores buffer the rise of land temperatures during the summer and the cold of temperatures during the winter.


The scientists fighting to save the ocean’s most important carbon capture system

Frank Hurd gently parted the curtains of giant kelp that reached upward through the cold waters of the North Pacific, looking for signs of life.

Kelp forests cover a quarter of the world’s coastlines, stretching from Antarctica to Australia, Mexico to Alaska, providing food and shelter for thousands of species, while sucking carbon from the atmosphere. But over the past decade, thanks to warming waters and overfishing, they’re disappearing.


For Florida’s corals, no escape from climate change

As temperatures rise and oceans acidify, coral around the globe is being increasingly threatened by the effects of climate change. But for most coral ecosystems, there may be some respite — scientists say that many may be able to migrate poleward to cooler waters as their original habitats become intolerable.


Sylvia Earle: My Wish? To Protect Our Oceans

By Manoush Zomorodi and others

Legendary oceanographer Sylvia Earle has been exploring and working to protect our oceans for more than half a century. Her message has stayed the same: we’re taking our oceans for granted.
