激励短句The United Nations Climate Change Conference takes place next week in Poland. About 20,000 people from 190 countries are expected to take part in the conference. There, world leaders will debate how to limit climate change — the weather events linked to slowly rising temperatures on Earth. They will discuss ways to reduce carbon emissions (排放物) and other pollution which, scientists say, can give ri to longterm changes to our planet.
For environmentalists, one area of concern is South America's Amazon rainforest. Brazil holds about 60 percent of the Amazon rainforest. It is also the most biodiver country on Earth, with more than 56,000 species of plants, 1,700 species of birds, 695 amphibians, 578 mammals, and 651 reptiles. Studies have shown that the Amazon takes in as much as 2 billion tons of carbon dioxide a year and releas about 20 percent of Earth's oxygen.
Scientists wonder whether the rainforest will be protected under Brazil's next president, Jair Bolsonaro, who began to take office on January 1, 2019. Bolsonaro had said that his country should withdraw from the 2015 Paris Agreement. Under the agreement, most nations promid to reduce carbon emissions by 37 percent over 2005 levels by the year 2030. The presidentelect claims a mandate (授权) from voters to develop land for agriculture and other purpos. He said that Brazil's rainforest protection is standing in the way of economic success.
《最后一课》Scientists say deforestation is a major reason for climate change. Studies have linked rising temperatures to the destruction of forests. Scientists worry about the future of the Amazon. New Brazilian government records show the speed of deforestation has incread over the past year.
Carlos Nobre, a climate scientist at the University of So Paulo, told the Associated Press that it is almost impossible to say just how important the rainforest is to the planet's living systems. Some scientists call the Amazon “the lungs of the planet”. They liken it to human lungs. Each tree takes in and stores carbon dioxide from the air around it. The trees also relea the oxygen we need to live.
cat的音标 The Amazon, the world's largest rainforest, also creates weather. Billions of trees pull up water through their roots. Then the trees relea water vapor into the air. The vapor forms a thick mist, made up of tiny drops of water. The water particles move up into the clouds and later return to earth as rain. Scientists estimate that the Amazon creates 30 to 50 percent of its own rainfall.
During the election campaign, Bolsonaro promid to ea protection for areas of the Brazilian Amazon t aside for native peoples and wildlife. He said that indigenous lands and nature rerves restrict economic growth.“All the rerves cau problems for development，”he said. The presidentelect also talked about taking away the power of Brazil's environmental ministry to enforce laws for protecting the environment.
Paulo Artaxo is a professor of environmental physics at the University of So Paulo. He said that if Bolsonaro keeps his campaign promis, then “deforestation of the Amazon will probably increa quickly — and the effects will be felt everywhere on the planet”．
However, natorelect Luiz Carlos Heinze, noted that farmers are not invaders (侵略者), but producers. He blamed the past administrations for supporting native rights at the expen of farmers. “Brazil，” he said，“will be the biggest farming nation on Earth during Bolsonaro's years.”
Scientists warn that if the Amazon and other rainforests lo too many trees, this could affect rainfall and global climate. Nobre and others estimate that the “tipping” point (引爆点) for the Amazon system is 20 to 25 percent deforestation. Without enough trees to support the rainfall, the longer and bigger dry ason could turn more than half of the rainforest into a tropical grassland.
