The environment pollution was more and more serious today. We have no clean water to drink it because of water pollution. And when trees cut down, some animals disappear. There is more and more dirty smoke in the air. People’s health has been great affected by air, noise and water pollution. Many people have died of diseases causing by pollution. In order to live the better life, it’s time for us to protect our world.

Firstly, we shouldn’t throw away rubbish everywhere. And we should recycle, reduce and reuse things, that saves money and reduces pollution. Use things so long as possible. Don’t use plastic bag. Besides, we must plant more trees and stop people cutting it down. We hope our world will be more and more beautiful.

Every year, more than 13 billion plastic bottles are sold in Britain. All of them     1     (use) only once, and only half of them are recycled.

Some think plastic bottles should be banned(明令禁止).     2     think they should be recycled. Others think a returning plan should be brought in to avoid the     3     (pollute) of rivers and seas. That is to say, people will get up to 20 pence back every time they return     4     bottle. A returning plan for bottles is already     5     (success) in Germany, where 98.5% of plastic bottles are returned.

    6     (lucky), there are already signs that things are changing for the better. Last year, Selfridges stopped     7     (sell) single-use water bottles. London Zoo announced that it would also ban them. It sold 155,000 plastic bottles of water last year. Now it will sell only reusable plastic bottles,     8     can be filled by visitors from taps. Families visiting beaches this summer are being asked to take part in a plan called “Return To Offender”. The idea is     9     (post) plastic bottles and other litter they find back to the     10     (company) that made them, using their freepost addresses.

Single-use plastic bags are used at most a few times before they     1     (throw) away. It takes them hundreds of years     2     (break) down. Many of these bags end up in the ocean where larger ones can trap sea creatures, such as turtles and dolphins. Over time, the bags fall apart into countless tiny pieces, and fish can     3     (accidental) eat some of them. Now, lots of     4     (country) and regions are taking action to ban the sale of such bags to stop people using them.

8 . The Blue Planet Ⅱ's latest episode focuses on how the plastic is having a destructive effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastics in their stomachs. Indeed, oceans are drowned in plastics.

Though it seems that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade when plastic packaging began gaining popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

We put all these plastics into the environment, but we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. The ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastics in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see the ocean plastic as a disaster, worth being mentioned in the same breath as climate change. But the ocean plastic is not as complicated as climate change. There are no ocean trash deniers(否认者), at least so far. To do something about it, we don't have to remake our planet energy system.

This is not a problem where we don't know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things may seem ordinary, like using a reusable bottle or a reusable bag, but when taken collectively, these choices really do make a difference.

Traditionally, livestreamers sell delicious snacks or local goodies. But     1     recent livestream event in Tibet autonomous region did something different. Waste plastic bottles,     2     are regarded as a great damage to the local environment, were sold for 0.5 yuan each, with the purpose of raising peopled     3     (aware) of Tibet’s pollution issue.

According to the Sohu website, in 2019, about 40 million tourists visited Tibet, which in consequence left about 360 million plastic bottles     4     (throw) in branches, on cliffs and in rivers. Not only does the white pollution cause serious threat to the delicate ecosystem     5     the death of local animals.

Over the past few years, more than 5,000 volunteers of different ages and from all walks of life     6     (participate) in the anti-white pollution campaign. They carry out over 2,000 clean-ups to collect 200,000 bottles left by tourists each year. Then the bottles are sorted by color and shipped inland     7     (make) raw materials. Roughly, each bottle costs about 0.5 yuan.

The livestream has successfully involved more people     8     the anti-white pollution campaign. People can scan QR code and donate money to encourage more people to collect bottles. It’s really a meaningful event and helps to make     9     possible for us human beings to coexist with nature     10     (harmonious).
