As climate change affects the planet, the world is turning to seaweed (海草)as a possible settlement and play a huge role in fighting climate change. It is used to create natural fuel and renewable plastics. It helps improve oceanic ecosystems.
People think of forests as the best defense(防护)against climate change. But some researchers say seaweed is a better settlement. Unlike trees, seaweed doesn't need fertilizers or fresh water. It grows faster than trees do. And it doesn't require any land. Most importantly, it absorbs carbon from the environment.
Seaweed could also become a key global food source. Many worry about the environmental influence of eating meat. Could seaweed farms provide enough protein（蛋白质）for the world? Carlos Duarte, a professor of oceanic ecology thinks so. When you look at how we are going to feed the world population by 2050, in a way that doesn't harm the environment, there is only one pathway," he says. "Seaweed farming."
In the past decade or so, global seaweed production has doubled. In British Columbia, seaweed farming becoming popular. For thousands of years, First Nations people, the native people of Canada, have farmed on land and in the ocean. Seaweed farming helps them create economies of their own that agree with their traditions. Their role has always been to connect with the land and repair it.
Seaweed might fight climate change but it isn't without risks. If it isn't harvested, it can go bad and give off carbon back into the air or water. Growing too much of it could also affect the amount of light that reaches species living deeper in the water. That would be dangerous for underwater ecosystems. So some scientists think seaweed can be a part of the settlement to climate change, but it's not a perfect one on its own.
