“People have discovered seaweed. They’ve discovered us.” At a coastal community in British Columbia, Canada, 84-year-old Louis Druehl is guiding *The Kelp Express* along the shore (海岸). For 51 years, the boat has been taking him to Kelp Bay. There, ropes of seaweed are growing under the water’s surface. Seaweed is Druehl’s life. He has studied it, farmed it, cooked it, and written a book about it. Over the years, Druehl has seen interest in seaweed rise and fall.
Many people think of forests as the best protection against climate change. But some researchers say seaweed is a better way. Unlike trees, seaweed doesn’t need fertilizers (肥料) or fresh water. It grows faster than trees and doesn’t need any land. It helps balance ocean ecosystems. And it takes in carbon from the environment.
Seaweed could also become a key food source in the world. Many people worry about the environmental effect of eating meat. Could seaweed farms provide enough protein (蛋白质) for the world? Carlos Duarte, a professor of marine ecology, thinks so. “When you look at how we are going to feed the world’s population by 2050, in a way that doesn’t harm the environment, there is only one way to do it,” he says. “Seaweed farming.” In the past ten years or so, global seaweed production has doubled. In British Columbia, there’s a long line of seaweed farmers waiting to learn from Louis Druehl.
Seaweed might fight climate change, but it also comes with risks. If it isn’t collected, it can rot (腐烂) and put carbon back into the air or water. Growing too much of it could also affect how much light reaches species (物种) living deeper in the water. That would be dangerous for underwater ecosystems. Some scientists say that seaweed can be part of the solution to fight climate change, but it’s not a perfect way on its own.
