题目

 阅读理解Any image taken from space confirms that we live on an ocean planet. How strange that we call our planet "Earth," derived from a Germanic word meaning "the ground," when more than 70 percent of its surface is covered by ocean.We need more people to see the sea. Right now, less than 3 percent of the ocean is considered highly protected. Experts urge that at least 30 percent be protected to safeguard marine(海洋的) ecosystems, which in turn will help protect our health and well-being. The ocean supplies more than half our oxygen, absorbs carbon dioxide, regulates our climate, and supports much of the world's economy. We need it a lot more than it needs us.Take Florida, for example, one of the United States' recreational hot spots. It's bordered by the Florida Reef Tract, North America's only living coral barrier reef and the third largest in the world. Home to more than 500 species of fish, the reef is also essential to the Sunshine State's economy, generating an estimated $1.1 billion annually in tourism. The reef buffers(保护) the coastline, too, since health y coral reefs absorb 97 percent of a wave's energy. Three-quarters of Florida's 22 million people live along the coast, and the Florida Reef Tract provides more than $650 million in combined economic activity and flood protection.A November 2022 study from the University of Miami has found that 70 percent of Florida's coral reefs are experiencing a net loss of reef habitat. Directly facing these concerns is what I mean by seeing the sea—the good, the bad, the important. Knowledge is power, and we can use it to inform our choices, from traveling more mindfully, to examining how we run our businesses, to voting. "No one can do everything, but everyone can do something," Sylvia Earle, oceanographer and National Geographic Explorer at Large, is fond of saying.The ocean is a remarkable teacher, and it's never too late to start learning. （1） What does the sea do for our human?
