Can Seaweed Survive Climate Change?

Seagriculture EU 2024

For this week’s video pass along, we travel to the island of Palawan in the Philippines, courtesy of @Context_news. Families there have been championing seaweed for over 30 years — growing seaweed cuttings on ropes in the ocean and harvesting them to make chips, noodles, and carrageenan, a valuable additive. One of the biggest items on their agenda these days is preparing their seaweed to survive climate change.

In recent years, seaweed farming has become the fastest-growing form of aquaculture in the world, in large part due to its many potential environmental benefits, like absorbing excess nutrients in the ocean and storing carbon on the seafloor. But as a crop threatened by warming temperatures and volatile weather, it’s not immune to the very problems it might help solve.

As farmers experiment with typhoon warning systems and deep-sea farming, scientists are cultivating climate-resilient seaweed strains in the lab. What they’re learning may help researchers better understand the costs of scaling seaweed around the world, and whether it can be the solution to climate change that they hoped for.

  • June 14, 2024: Engineers at the University of California San Diego have developed microscopic robots, known as microrobots, capable of swimming through the lungs to deliver cancer-fighting medication directly to metastatic tumors. This approach has shown promise in mice, where it inhibited the growth and spread of tumors that had metastasized to the lungs, thereby boosting survival rates compared to control treatments.

  • June 12, 2024: The PROTEUS consortium of 11 international partners, funded by the Circular Bio-Based Europe Joint Undertaking, intends to establish the first industrial-scale biorefinery for brown seaweeds. This facility will enhance sustainable production of bio-based ingredients from Laminaria hyperborea, an untapped European renewable resource, meeting global demand in food, feed, personal care, and industrial sectors.
