The Amazon Rainforest breathes life into the planet by fixing carbon and producing over 20 percent of all the 【小题1】 (Earth) oxygen.【小题2】, it is often known as the “lungs of the planet”. Moreover, the Amazon Rainforest is a treasure house of species that can【小题3】 (use) for food or medicine. Yet there is one major danger to these【小题4】 (replaceable) plants and animals: us. Over the past two years, about 17 percent of the rainforest【小题5】 (disappear) due to human activities such as agriculture and cattle farming. As the impact of human activities continues to grow and the list of species in danger of【小题6】 (extinct) becomes longer, we are left with a question: Can we afford【小题7】 (damage) the “lungs of the planet”?

A Tsinghua professor is leading authority on tackling global warming and public attention has been drawn 【小题1】 him for his clear message, Yang Feiyue reports.

Global warming, carbon footprints, the 2-degree limitation for temperature 【小题2】 (grow)...all those abstract terms are 【小题3】 (vivid) brought to life in Guan Dabo’s lecture.

In addition to his academic research and teaching work, the climate change economics professor from the Department of Earth System Science at Tsinghua University,has made a speech to 【小题4】 public.

“I’m a strong believer in environmental protection 【小题5】 (be) up to every individual,” Guan says.

His speech last year on I Am A Scientist, a multiplatform series of online articles and videos organized by the China Association for Science and Technology, 【小题6】 (enable) the audience to better understand how carbon consumption matters and relates to their own lifestyles.

“Since the industrial revolution, the burning of fossil fuels 【小题7】 ( release) much carbon dioxide into the atmosphere. If we want to reduce the risks, we need to limit global warming to 2 【小题8】 even 1.5 degrees by the end of this century,” he adds.

In 2000, he chose 【小题9】 (pursue) environmental management with science at the University of Leeds in the United Kingdom. “I am naturally drawn to the environment, 【小题10】 is closely connected to our life,” he says.

Nowadays, the life of many people in the world 【小题1】 (affect) by global warming. For example, greenhouse gas has a bad effect 【小题2】both people and environment. The earth’s surface temperature 【小题3】 (go) up by about 1 degrees centigrade in the past 100 years. As a matter of fact, we may feel that we can hardly put up with the extremely hot summer and we can’t get 【小题4】 (accustom) to warm winter. The rise of the earth’s surface temperature has affected human health, the existence of creatures 【小题5】the balance of ecosystems. There is no doubt 【小题6】 it is human activities that result in the bad environment. As a 【小题7】(consequent), conditions permitting, all countries in the world should spare no effort 【小题8】(improve) our environment. Even if our effort is limited, it will 【小题9】 (eventual) make a great difference if we keep on 【小题10】 (work) together to deal with global warming. Without all people’s joint efforts, what would our future be like?
