Algae - the superplant
With the world's population expected to reach the 9 billion mark by around 2050, specialists of all stripes are concerned about feeding the next generations.
Luckily, there is an alternative marine solution, one that could significantly help, if not guarantee, mankind's survival: algae, which has been popular in Asian cooking for centuries. This abundant resource is even more important considering that it can be cultivated or harvested in the wild.
Seaweed, for example, is a type of algae that has been eaten for centuries, but only 35 countries commercially harvest it today. Spirulina cyanobacteria is already eaten as a food supplement and several companies are trying to turn other forms of algae into a human food source.
Farming these organisms in the right way could even help counter some of the effects of climate change on the rest of the food chain. For example, growing more seaweed lowers the amount of CO₂ in the surrounding water, reduces acidification, and improves the environment for oysters and other shellfish. Managing seaweed harvest correctly will also maintain the dissolved oxygen and nutrient levels in the water, contributing to the overall health of the ocean.
