Ban the Bag!

Standing in line at the grocery store last week, I watched the woman in front of me buy a tube of toothpaste. As the clerk placed her purchase in a plastic bag, I couldn’t help wondering how long it would take for that bag to end up in the trash. Then I noticed the big purse the woman was carrying and wondered why she had needed a plastic bag at all.

People have come to rely on plastic bags as everything from shopping bags for groceries to trash-can bags. Although plastic bags can be recycled, only about one percent of those used in the United States are. Instead, after helping people transport items from one place to another, most are thrown away. They end up in landfills, where it can take a plastic bag up to a thousand years to decay. Some bags end up elsewhere in the environment, sticking to trees and fences, blocking rivers and oceans, or floating along city sidewalks.

Plastic bags harm the environment in several ways. First, they break down into particles that pollute our soil and water. Because most plastic bags are made of polyethylene, a product derived from crude oil (原油) or natural gas, they waste nonrenewable resources. Plastic bags can also harm animals. Scientists estimate that more than one million sea animals, including whales, seabirds, and turtles, die each year from intaking or becoming stranded in plastic.

People all over the world are starting to recognize the problems associated with plastic bags. Countries such as China, South Africa, Switzerland, and Uganda are taking action and banning the bags. Other nations, including Italy and Ireland, have been trying to restrict the use of plastic bags by taxing them. In the United States more and more communities are ridding themselves of plastic bags. Now more and more people are also purchasing inexpensive, reusable bags and using them when they shop. If we all take this simple step, we can be a part of a “green” revolution.

【题目】 China and India are leaders in improving global(全球的) tree cover, a new study based on NASA research showed.

They took a 31.8% part together of the total global new leaf area between 2000 and 2017. China played a major role, adding 25% to this increase, and India added 6.8%, followed by Canada and Russia. The study in the Nature Sustainability journal shows that more than 5.5 million square kilometers of green leaf area was added globally. Since 2000, there has been a five-percent increase in global green cover, it said.

“The greening over the last twenty years shows an increase in leaf area on plants and trees which is as large as the area of the entire Amazon rainforest," Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability. Large plantation activities to protect forests in China contributed nearly 42% to the country's green cover, and agriculture added another 32%. In India, 82% of the increase in leaf area was because of agriculture.

“China and India take up one-third of the greening, but hold only nine percent of the planet's land area covered in green plants," Chi Chen told NASA Earth Observatory. “That is a surprising finding, considering the land degradation(退化) in countries with large populations.”

Boston University's research team first detected an increase in global green cover in the 1990s but were unsure about what contributed to the increase. Finally, with the help of NASA's Terra and Aqua satellites research, they managed to find out the increase in leaf cover from different areas and places.

1Which country increased the largest part of the new leaf area?

2For what purpose did the author mention the Amazon rainforest?

A.To show how great the achievement was.

B.To show the importance of rainforest.

C.To explain what difficulties we have now.

D.To explain the reason for increasing forests.

3According to paragraph four, the following statements are true EXCEPT_______.

A.China and India have large populations and land degradation problem

B.about 9% of the planet’s greening is in China and India

C.China and India are leading in the global green cover increase

D.the leaf cover area in China and India is still limited if viewed globally
