Seaweed has definitely been getting its fair share of spotlight, having been touted as a “sustainable crop of the future.” But have you ever taken a closer look at what seaweed is, and how to incorporate it more into your sustainable lifestyle?
What is seaweed?
Seaweed is a type of macroalgae found in our rivers, oceans and lakes with thousands of seaweed species around the world. Some of the more common types include red seaweed, brown seaweed, green seaweed and Japanese kelp (known as ‘wakame’).
However, don’t confuse seaweed with kelp. The two terms are sometimes used interchangeably, but kelp is, in fact, just a type of seaweed.
Why is Seaweed a Sustainable Crop?
Seaweed plays an important role in balancing marine ecosystems. The aquatic plant is also essential to maintaining biodiversity because it offers food and protection for many species. For example, kelp forests shelter species from jellyfish and crabs to grey whales, while also acting as a barrier against storm surges and tides, minimising the impact of strong currents in coastal areas.
Another reason seaweed is a sustainable crop is that seaweed is a ‘carbon sink’. This means that it absorbs carbon dioxide (Co2) from our atmosphere – up to 200 million tonnes of Co2 per year, in fact! Fun fact: the carbon stored by seaweed is called ‘blue carbon’.
Seaweed’s many uses
A large portion of farmed seaweed is intended for consumption, and seaweed has been a staple in East Asian diets for many centuries, primarily because of its exceptional nutritional benefits. The macroalgae is high in omega-3s and contain important minerals including sodium, calcium, magnesium and phosphorus.
Apart from obvious examples like sushi, seaweed is also an essential flavour enhancer in Asian cuisine and often used in stocks or sauces.
Seaweed also has excellent hydrating and exfoliating properties, making it ideal as a skincare ingredient. Skincare products with seaweed extracts usually help with hydration, anti-aging and exfoliation.
Of course, not all types of seaweed are grown for commercial consumption. Many countries also grow seaweed to restore marine habitats and to clean up the oceans.
