中考真题2024年广东省深圳市阅读理解B篇-海洋警钟：大型鱼类濒临灭绝，人类行动迫在眉睫！
After a 10-year project to count tuna and other large fish in the world's oceans, scientists have made a very surprising discovery: these fish are almost gone. Because of too much fishing, almost 90 percent of the worldwide population of large fish—the ones we usually eat—has disappeared. If we don’t act, these animals will totally disappear. That will influence every animal in the ocean.
The demand for fish is growing. Almost a billion people around the world get their protein (蛋白质) mostly from fish. Doctors praise seafood for being low in fat. But what seems like a healthy choice for humans is causing a disaster to our oceans. “People are consuming (消费) too much,” says Lance Morgan, a scientist at the Marine Conservation Biology Institute.
A dish of tuna in restaurants costs more than just one animal's life. When fish like tuna disappear from the ecosystem (生态系统), the ocean’s food chain (链) breaks down. Animals such as sharks, which normally eat tuna, may die because they find no food.
The news may be scary, but taking action from now on can prevent harm that hasn’t happened yet. World organizations are ordering countries to stop fishing too much. The Monterey Bay Aquarium gives seafood choices to anyone hoping to keep healthy without destroying the environment.
“If you care about wildlife, first spend time and think about your own values and beliefs,” says Morgan. “Then decide what you’re going to eat.”
