Along the picturesque coast of South Africa stretches one of the most fascinating and unknown ecosystems on earth: the kelp forest. Consisting of meter-long brown algae, it stores as much CO2 as the Amazon rainforest. It is also home to numerous animal and plant species and a paradise of biodiversity: from crabs and starfish to small sharks and octopuses, many creatures use the kelp forest as a refuge. Kelp is also a healthy source of food, which is why the brown algae is currently experiencing a hype in South Africa.
