    Some scientists were studying sea turtles in Costa Rica in Central America. Suddenly they found one turtle had something sticking out of its nose. It could not breathe. At first, the scientists thought it was a worm. But when they pulled the object out, it was a plastic straw(吸管）.

After the scientists made sure the turtle was healthy, they helped it back into the water. They posted a video of the rescue on the Internet. When people saw it, they were shocked.

The video motivated Diana Lofflin to start StrawFree.org. The group is in California. Its goal is to make people aware of (意识到)the harm plastic straws cause to the environment. Lofflin hopes people will find alternatives(可选择的事物）to plastic straws.

Sipping from a straw is fun. But think twice. Giving up that plastic straw can help protect the environment. Saying no to a plastic straw is a way to make a difference in the world.

A movement to ban（禁止）plastic straws is growing. In California, it is illegal for food servers to give straws to customers who don’t ask for them. Seattle, Washington, has banned all plastic utensils(器具).

Plastic straws are put out for the taking in many restaurants. But some states no longer allow it.

Starbucks is banning plastic straws. The company says it will stop handing out plastic straws in all its stores by 2020. With 28,000 stores, that’s about 1 billion fewer straws a year. How will you sip your drink? The company has made a new lid for its cups, like those used by little kids. Unlike straws, the new lid can be recycled.

Nancy Wallace works for the National Oceanic and Atmospheric Administration, in Washington, D.C. She says schools should reduce the amount of plastic they use. Kids must do their part, too. Plastic litter gets into rivers, lakes, and oceans. If fish and other animals eat it ,they will be killed. Wallace says : “We’re pinning our hopes on the next generation to help solve this problem.”
