2 . Meat is crucial for feeding the planet, leading scientists have said, as they warned it is not more environmentally-friendly to go vegan (素食).
Prof. Geoff Simm, Director of Global Academy Agriculture and Food Security at the University of Edinburgh, said, “I think livestock (家畜) farmers do feel they are being demonized (妖魔化).” Often the argument is made that going vegan would minimize land use, but the modelling studies that have been done demonstrate that’s not the case. We feel that while livestock production has a range of economic, social and environmental costs and benefits, the costs have perhaps been receiving far more attention recently than some of the benefits. Meat has massive social benefits. It’s an important source of dietary protein, energy, highly bioavailable micronutrients (微量营养素), even small amounts of animal-sourced food have a really important effect on the development of children, in the developing world on their cognitive and physical development and they are really important.
Prof. Mike Coffey, from Scotland’s Rural College, added, “It’s completely unnecessary to go vegan. If everybody went vegan it would be devastating for the UK environment. Animals bred for food help boost biodiversity.”
Researchers are currently attempting to breed more environmentally friendly cattle, which grow faster and eat less, which could further reduce the sector’s carbon footprint by reducing the amount of methane (甲烷) released by cows.
Prof. Coffey said that the difference in methane emissions from best and worst cattle was about 30 percent and that if all UK farmers used the most efficient animals this could reduce carbon emissions by nearly a third. But Prof. Coffey said the next stage will be trying to measure the methane given off by different breeds of cattle to find which are the lowest emitters. Prof. Coffey said that soon shoppers could be able to check meat labels to find out how much environmental impact their food has had. He added, “My expectation is that at some point in the near future there will be product labels that relates to the efficiency or carbon impact of the food.”
Professor Andrea Wilson, also of Edinburgh University, said more research was needed into the impact of veganism (绝对素食主义). She added, “We know a lot about the livestock sector because people have looked at it. We actually know very little about the vegan sector. The danger is we demonize one and jump too quickly to the other.”

3 . The endangered pandas in Qinling Mountains might face a new threat: the loss of their food—bamboo, which makes up 99% of their meals.
Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature and Climate Change warned that they may soon find their food gone because most of the bamboo in Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.
A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature increases 3.5 degrees worldwide by the end of the century.” said Liu Jianguo, one of the reports’ authors. He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening around the world.”
In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves. “But it is far from being enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from World Wildlife Fund.
The Qinling Mountains are home to about 360 pandas. That is about a quarter of the China’s wild panda population. In addition, about 435 are living in research centers and zoos in China.

| A．The changes of temperature is sensitive to bamboo. |
| B．China needs more help from World wildlife Fund. |
| C．China is making great efforts to protect the pandas. |
| D．It is difficult to control the temperature rise within 3.5 degrees. |
| A．About 1,500. | B．About 720. | C．About 360. | D．About 1,900. |
| A．Necessity to Change Pandas’ Food | B．A New Threat Faced by the Pandas |

8 . Young students can, and do, make a big difference. As an educator, you have the opportunity to spark (触发) a passion in students that will drive them to do their part to take care of the Earth. Here are activities you could add to your lesson plans to inspire your students on Earth Day:
Make signs for school and at home
Sometimes we just need a little reminder to help us change our habits. Have students think about what they can do at school and at home to help the environment and how they can encourage others to change their habits.
Make a video or presentation urging others to take action
Students can make a bigger impact if they influence others to do their part to protect the environment. Putting together a video or presentation also helps them internalize the material itself — they need to understand it before they can explain it to others. Presentations can be given in the classroom or even to the whole school. Eventually, they may be able to present their lessons and research at a local conference.
Show them examples of other students making a real difference
It's important for students to see examples of young environmentalists so they know they don't need to wait until they're older to make a difference. Learning about the work these young people are doing can give your students new ideas for how to protect the environment. It can open the door of possibilities for how to think about finding solutions to problems they can help solve.
Earth Day isn't just on April 22. It's every day. How will you celebrate Earth Day and help students make a difference year-round?

The famous environmentalist, Professor Jin , was invited deliver a speech in our school last Friday He started with an universally accepted theory explaining how the Earth began. We were shocking that there was so many kinds of living things on the planet a long time ago, Besides, he also showed how the disappear of some species happened later. It was human activities that large changed the global environment. He pointed out we should attach great importance to protect the environment, which decided that we would be able to continue to live on this planet in the future. I was deeply impressed by her speech and I think of it is important to protect our only home.
