Sea turtles (海龟) are cute animals, but they are in danger of going extinct (灭绝的). That's mainly because many people kill them for food.

    But this news may stop those people: Dr Nichols and other scientists have found that sea turtles take in a lot of pollution from the sea. It is bad for both sea turtles' and humans' health. Many people get sick and even die from eating sea turtle meat.

    People in America don't usually have sea turtles on their dinner table. They think eating sea turtles is gross (令人恶心的). Also, all the seven kinds of sea turtles are protected by law. “But some people around the world still eat them,” explained Dr Nichols. “At first we wanted to save sea turtles; now we want to save people, too.”

    Dr Nichols wants to send theinformationto people who still think sea turtle meat is good food. And he wants people to understand a bigger message: we should protect the sea. “The health of the sea, the health of the animals in the sea, and our own health all have close relationships. For a long time we didn't really realize it,” said Dr Nichols. “Now it's clear that a clean sea is really good for us because of the food we eat from there.”
