According to the wildlife trade monitoring organization—TRAFFIC， about one million pangolins （穿山甲） were killed from 2000 through 2013， mainly for their scales （鳞片）， which are used in medicine. Pangolins are sensitive creatures and picky eaters that only eat certain kinds of ants， a diet that’s very difficult to copy in the food chain.

“In the last decade， there’s been a huge growth trade in pangolins between continents， especially their scales，” says Dan Challender， chair of the pangolin specialist group. Previously， most pangolin killing happened within Asia， he says. This change means that Asian pangolins are becoming difficult to find but that the value of the scales makes it worth the extra cost to take pangolins from Africa to Asia secretly.

All eight types of pangolins， four in Africa and four in Asia， are in danger of extinction due to the illegal trade. International trade in the four types of Asian pangolins has been banned （禁止） since 2000. In the past few years， a ban on international commercial trade in all eight types has gone into effect. It was voted by 183 governments that are parties to the Convention on International Trade in Endangered Species （CITES）， which is in charge of cross-border trade in wild animals and their parts.

Pangolins are eaten as bushmeat in western and central Africa and by some local groups in South and Southeast Asia. Their parts also are used in Ghana， Nigeria， South Africa， and elsewhere in sub-Saharan Africa as traditional medicine. But they are now endangered. Perhaps no pangolins can be seen when our next generation grow up.

Imagine an area 34 times the size of Manhattan. Now imagine it covered ankle-deep （齐踝深的） in plastic waste—a total of about 19 billion pounds of garbage. 1 .

“We’re being overwhelmed （淹没） by our waste，” said Jenna Jambeck， an environmental engineer who led the study that determined this surprising number. 2 ， unless something is done to stop the tide of garbage.

Plastic—a widely-used material—has in many ways been a benefit to humans but it has also caused a growing problem. Today， plastics are the No.1 type of garbage found in the sea. Ocean Conservancy， a nonprofit that organizes an annual coastal clean-up event worldwide， said plastic waste makes up around 85 percent of the garbage collected from beaches and oceans.

Ocean Conservancy says plastics are believed to threaten （威胁） at least 600 different wildlife species （物种）. 3 . A growing body of evidence suggests humans are consuming plastics through the seafood we eat. A research suggests some plastics could be poisonous to humans， and could potentially increase the risk of health problems.

4 . At the Economist World Ocean Summit this week， ten nations announced to reduce plastic sea litter as part of UN Environment’s CleanSeas campaign. 5 . Corporations also have a role， as do individuals. We can start by thinking twice before using single-use plastic products—and when we do use them， we should take care to properly throw them off or recycle.

A. The following is what we should do

B. And it’s not just wildlife that’s threatened

C. And this figure is likely to double by 2025

D. But it’s not just countries that need to do their part

E. By 2050， that figure is expected to rise to 1，000 pieces

F. That’s how much plastic waste ends up in our oceans every year

G. All of us have an important role to play in dealing with the problems
