Why Help Kelp?

We know the 'kelp highway' helped human populations expand from Asia in the Americas some 20,000 years ago.

Across the Pacific, kelp harvest has played a significant role in Japanese, Korean and Chinese economies, and has been an important commodity since the 8th Century.

For millennia, people living off our ocean's resources have known the value of kelp forests but even to this day, they remain a great example of an overlooked and under-appreciated ecosystem. 

In Medieval Europe, kelp was used to fertilize soil and increase crop yields, and even treat goiter. For centuries it was also used to fortify building materials.

In the 21st Century, kelp forests have become the main source of alginate - a now common food and medical additive. Kelp's now used to make many products including toothpastes, shampoos, salad dressings, puddings, cakes, dairy products, frozen foods and even pharmaceuticals.

Its vast array of known health benefits include aiding healthy nails and blood vessels, reducing hair loss, easing constipation, helping with diabetes and weight management and treating gastrointestinal ulcers.

Throughout this entire time, kelps have supported ecosystems teeming with life and important fisheries of abalone, lobsters and many types of fish.

But more than this, through their prolific productivity, kelp forests draw carbon from the atmosphere (known as a 'carbon sink'), exude oxygen, and help reduce nutrient pollution in our oceans - enhancing biodiversity and ultimately helping the planet fight climate change.

Although many of the world's kelp forests are in decline - mostly due to rising ocean temperatures - not all hope is lost. There's still time and opportunity for us all to step-up and #HelpTheKelp!

So, what can we do?

How? A simple way is to cut down the amount you drive - by taking public transport or cycling. You could even 'go electric' whether it's your car, stove or using solar at home. Avoiding single-use plastics can also keep high manufacturing emission levels down.

What can you do? Vote for policies in your area that help drive sustainability missions, such as replacing fossil fuels with clean energy or supporting the creation and management of local marine parks.

How? Take a virtual deep dive! There are many online resources available, such as our Knowledge Hub, to help us understand the significance of kelp. Just be sure to take this one step further and share what you find with your family and friends!

The Kelp Forest Challenge is a global movement to raise our connection to the ocean and ultimately protect and restore 4 million hectares of kelp forests by 2040. Anyone can get involved, it doesn't matter if you are a snorkeller, CEO, scientist, artist or ocean lover.
