【题文】完形填空
“When it comes to Earth, there’s no time to waste,” says the Earth Day Network. And that is right. Protecting our environment is very important, and World Earth Day was
in 1970 to raise people’s environmental awareness. On April 22, People around the world celebrate Earth day.
Every year there is a special
, and this year it is “Trees for Earth”, so Earth Day will be all about planting trees. Their goal is to plant 7.8 billion trees
the next five years.
That’s a big goal, and you might wonder
trees are so important. Well for one, they can help stop climate change. Carbon dioxide (二氧化碳) is a chemical in our atmosphere, but
make too much of it. Each person makes about 2.3 tons a year, which is bad for the environment.
Well guess what! Trees
carbon dioxide and protect the air quality. Planting new trees is important because people cut down
trees. Last year, there were 3 trillion(万亿) trees in the
, about 139 billion in China. But according to Time, the world’s total number has been
cut in half since human civilization (文明) began. That’s because 15 billion trees are cut down every year.
So we need to plant more to replenish (补充) the ones we’ve lost. One tree can take in 48 pounds (21.8kg) of carbon dioxide per year. And it’s still one of the cheapest and
ways to get rid of carbon dioxide.
But don’t forget that you can also help the environment by cutting down on how much energy or water you use every day. Every little thing helps!
