From Amazon rainforest According to a study, nearly 20 percent of carbon dioxide was released into the atmosphere in the past decade compared to the so-called The green lungs of the planet Can be included. Thursday in the magazineThe Nature of Climate Change“A published study compared the amount of carbon dioxide absorbed by the forest with that of carbon dioxide from cutting, burning and destroying.

Figures showed for the first time that “the Brazilian Amazon rainforest has tended and is now one Net source It is, “said the co-author Jean-Pierre Winron Of French nationality Agricultural Research Institute (Inra). “We don’t know at what point this change will become irreversible.”

The study also shows growing Destroy the forest with fires and lumberjacks.

Healthy ecosystems play a critical role in Combating climate change And increase in carbon dioxide emissions, which amounted to more than 40 billion tons in 2019. Over the past 50 years, plants and soil have absorbed about 30 percent of these emissions, and the oceans more than 20 percent.
