...Do we need to worry about oxygen?
No. Although some reports have claimed the Amazon produces 20% of the world’s oxygen, it is not clear where this figure originated. The true figure is likely to be no more than 6%, according to climate scientists such as Michael Mann and Jonathan Foley.
So should we still be concerned?
Extremely. The fires are mostly illegal and they are degrading the world’s biggest terrestrial (sống trên mặt đất, (thuộc) hành tinh trái đất) carbon sink and most important home for biodiversity (đa dạng sinh học). They also contribute to a more important trend, which is an alarming rise in deforestation (sự phá rừng, phát quang). Scientists say the Amazon is approaching a tipping point (điểm lật), after which it will irreversibly (không thể đảo ngược) degrade (xuống cấp) into a dry savannah (hoang mạc khô). At a time when the world needs billions more trees to absorb carbon and stabilise the climate, the planet is losing its biggest rainforest.
Is this the fault of the Brazilian president?
Jair Bolsonaro has made things a lot worse by weakening the environment agency, (cơ quan môi trường) attacking conservation NGOs and promoting the opening of the Amazon to mining, farming and logging. The far-right leader has dismissed satellite data on deforestation and fired the head of the space agency. But it is not solely his fault. The agricultural lobby is powerful in Brazil and it has steadily eroded the protection system that was so successful from 2005-2014. Deforestation crept up in the past five years under the previous presidents Dilma Rousseff and Michel Temer. The rate has accelerated rapidly in the first eight months of Bolsonaro’s rule.
