(2022·浙江温州考前模拟)We love the sea. We swim into it, live near it, build beside it, and even imagine about living under the sea. But we're terrified of it, too. For much of our history, we have turned to “hard engineering” to control the marine(海洋) environment and manage its influence on us. We build dams, sea walls and channels. But all these efforts seem to fail. The sea has a habit of taking back its own. And we suffer.
Johnston, a marine ecologist, is advocating for “blue engineering”—the marine version of the “green engineering” movement on land that has seen nations like Singapore building the walls and roofs of the concrete jungle with plant life.
We are expanding further into the marine environment. This practice does harm to marine ecosystems. We're loving the sea to death, but we've not been thinking about design of structures (建筑物) with respect to ecology. Some coastal structures create shade, which reduces the growth of seaweed. Bright lights at night confuse species such as turtles. That's why blue engineering comes in.
Throughout the world people are starting to turn things around. Researchers with the World Harbour Project are creating tiles(瓦片) similar to the natural structures found on rocky shores with 3D printing technology. These make more attractive homes for marine creatures. Researchers are also actively seeding these tiles with local seaweeds and creatures such as the Sydney rock oyster, which is particularly good at improving water quality. Twelve harbours around the world are taking part in this marine tile experiment, each working with their own unique marine life.
It's a far cry from the days when a huge number of old tyres were thrown into the sea to build “artificial reef (礁石)”. Those clumsy early attempts are now costing millions to remove, showing just how far we have yet to go in understanding how best to cohabit with the underwater world.
