Seaweed Could Be the Key to a Sustainable World, Researchers Say

The ocean has marveled scientists for centuries, and recently, Australian researchers have been looking at seaweed as a way to save the planet. The consequences of climate change are very real and very dangerous, and finding sources of sustainable energy, including food and fuel, has been a number one priority for researchers. It turns out the answer might just be right off the shore of Australia.

Seaweed Is Rich In Nutrients & Has a Unique Molecular Structure

Researchers have found that kelp and other types of seaweed can be an effective means to fight climate change. According to Dr. Pia Winberg, seaweed can become as important to civilization as nitrogen, lumber, wheat, and plastic if it’s properly harvested. That reasoning is based on the rich nutrient profile and molecular structure of seaweed species.

Due to its fast growth and ability to absorb carbon at incredibly quick rates (even faster than terrestrial plants), seaweed can be used in a myriad of ways. By farming it on a large scale, we can use kelp and its cousins to balance emissions, add a new farming branch, deacidify the oceans, and even look into new materials research.

A Promising Model for the Future

Incorporating seaweed not only in our diet but also in our agriculture cycles can be a gamechanger for our future, says Winberg. According to a recent study, if just 3.8% of California’s coastal waters are dedicated to kelp cultivation, it will be enough to absorb the emissions from its agriculture sector. The good news is that many people and businesses are already utilizing seaweed’s incredible qualities in their lives and work.

To Winberg and her colleagues, offshore seaweed cultivation in Australia is one of the best ways to show the benefits of large-scale kelp farming and all it can do to improve our collective future.
