Man did not have to think about the protection of his environment in the past. There were not many people on the Earth, and natural resources seemed to be unlimited.
Today, things are different.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries, waste products are still put into rivers or into the sea, and there are few laws to stop this.
We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
The world population will not rise so quickly if people use modern methods of birth control.

3 . The Last Straw?
Every second, the world uses 160,000 plastic bags — that is a total of over five trillion per year. Up to 99 percent of these plastic bags hang around for at least 1,000 years and pollute Earth. And yet, plastic bags are hardly a necessity in our lives. Of all the changes we could make to create a more sustainable lifestyle, a total ban on plastic bags should be simple.
At the beginning of 2021, Shanghai put in effect a ban on all plastic bags in shopping malls and supermarkets, as well as a ban on non-degradable plastics in many other areas. Over the years, individuals and companies have worked to replace plastic items, such as cups and straws, with paper ones.
Customers complain that paper straws often become soft and break before they can finish their hot drinks. Experts, however, have repeatedly stressed plastic substitutes (替代品) are not the ultimate solution, and that our consumption habits need a bigger change.
In college, one of my environmental science professors promoted a type of waste-free living. She carried around a small glass jar with her, and in it was all her trash she collected for the entire year. She was able to do this by bringing her own cup to Starbucks, her own bags to the shops, and never buying anything that came wrapped in plastic. Her food waste also became compost.
Plastic bags are incredibly easy to forget about when they become increasingly common.
| A．Clearly she demonstrated our ability to live a completely healthy life without creating a great deal of plastic waste. |
| B．Plastic bag litter has even caused great problems in some areas. |
| C．If they’re free to use and easily disposed of, they’re a mere tool that we don’t have to think about. |
| D．Some of these decisions have been met with criticism. |
| E．Unfortunately, such a high level of pollution doesn’t come without consequences. |
