Fires sweeping across the Amazon rainforest recently have been making the headlines as
scientists and environmental groups are worried that they will worsen climate change crisis
and endanger biodiversity(生态多样性)
As the largest rainforest in the world,the Amazon rainforest is often called "the lungs of
the world".It is also home to about 3 million species of plants and animals,and 1 million
local people.The vast area of rainforest plays an important role in the world's ecosystem
because it absorbs heat instead of reflecting heat back into the atmosphere.It also stores
carbon dioxide and produces oxygen,ensuring that less carbon is released,reducing the
effects of climate change.
"Any destruction of forest is a danger to biodiversity and the people who use that
biodiversity,"Thomas Lovejoy,an ecologist at George Mason University told National
Geographic."The great danger is that a lot of carbon goes into the atmosphere,"he stressed.
"In the midst of the global climate crisis,we cannot afford more damage to a major source of
oxygen and biodiversity.The Amazon rainforest must be protected,the UN Secretary
General said.
Data from the National Institute for Space Research show that a total of 71,497 forest
fires were registered in Brazil in the first 8 months of 2019,up from 39,194 in the same
period in 2018."We estimate that the forest areas in the Brazilian Amazon have decreased by
20 to 30 percent compared to the last 12 months,Carlos Nobre,a researcher at the
University of Sao Paulo,told German broadcaster Deutsche Welle.
Brazil owns about 60 percent of the Amazon rainforest whose degradation()could
have severe consequences for global climate.The extent of the area ruined by fires has yet to
be determined,but the emergency has gone beyond Brazil's borders.
