1 . Louis Druehl lives in Bamfield. He works at a seaweed(海藻)farm, where long ropes of seaweed grow under the water. He has been farming kelp since 1982, which is brown sea weed.
Druehl has studied seaweed for along time. He's even written a book explaining in detail what it can do for humans. Druehl says the world is turning to seaweed as a solution(解决办法)to climate change. "People have discovered seaweed," he said. "It has discovered us. It benefits humans, so we should take full advantage of it."
Seaweed can be used to produce energy and make plastics that can be recycled. Besides, it takes carbon out of the environment. This is good for the health of the planet. Some researchers say seaweed is even better for the environment than trees are. Seaweed doesn't need fertilizers. It doesn't need fresh water or land. And it grows fast. Seaweed could also be a global food source. Carlos Duarte is a professor of ecology. “To feed the world population by 2050, in a way that doesn't harm nature, there is only one pathway," he says. "Seaweed farming." Seaweed farming is not new. Native people of Canada have been farming it for thousands of years. But many of them have left to find other work. Now, the rapidly growing seaweed industry could bring jobs to many people. This includes those who lost their jobs during COVID—19.
Seaweed may slow climate change. But there are risks. When it rots(腐烂),it releases carbon. And too much seaweed could affect how much light reaches underwater creatures. Halley Froehlich works at the University of California, Santa Barbara. When it comes to climate change, Halley says seaweed “can be a part of the solution, but it's not a solution on its own" to climate change.
However, I'm on Druehl side. The industry of seaweed will surely have a bright future though some people are questioning its effects.
