Kelp forests provide an estimated value of $500 billion to the world and capture 4.5 million metric tonnes of carbon dioxide from seawater each year
Kelp forests provide an estimated value of $500 billion to the world and capture 4.5 million tonnes of carbon dioxide from seawater each year. Most of kelp’s economic benefits come from creating habitat for fish and by sequestering nitrogen and phosphorus., like forests on land, are numerous. The towering brown algae provide habitat for marine life, protect coastal areas from storms and sequester greenhouse gasses as they grow.
“Much like a plant on land, [kelp forests] are taking up nutrients, they’re taking up carbon dioxide, and using light to fuel their growth,” says Eger. By examining the amount of each compound stored in the plant’s tissue, they could determine how much the kelp was sequestering. They found that kelp forests generate a potential value between $465 billion and $562 billion per year worldwide, largely due to commercial fish support and the removal of harmful chemical substances. As part of their assessment, the team found that kelp forests absorb around 4.5 million tonnes of carbon dioxide each year, highlighting kelp’s potential as a “
