When will the Amazon hit a tipping point?

De acordo com o terceiro parágrafo, a Floresta Amazônica

Scientists say climate change, deforestation and fires could cause the world’s largest rainforest to dry out. The big question is how soon that might happen. Seen from a monitoring tower above the treetops near Manaus, in the Brazilian Amazon, the rainforest canopy stretches to the horizon as an endless sea of green. It looks like a rich and healthy ecosystem, but appearances are deceiving. This rainforest — which holds 16,000 separate tree species — is slowly drying out.
Over the past century, the average temperature in the forest has risen by 1-1.5 °C. In some parts, the dry season has expanded during the past 50 years, from four months to almost five. Severe droughts have hit three times since 2005. That’s all driving a shift in vegetation. In 2018, a study reported that trees that do best in moist conditions, such as tropical legumes from the genus Inga, are dying. Those adapted to drier climes, such as the Brazil nut tree (Bertholletia excelsa), are thriving.
At the same time, large parts of the Amazon, the world’s largest rainforest, are being cut down and burnt. Tree clearing has already shrunk the forest by around 15% from its 1970s extent of more than 6 million square kilometres; in Brazil, which contains more than half the forest, more than 19% has disappeared. Last year, deforestation in Brazil spiked by around 30% to almost 10,000 km2, the largest loss in a decade. And in August 2019, videos of wildfires in the Amazon made international headlines. The number of fires that month was the highest for any August since an extreme drought in 2010.

De acordo com o terceiro parágrafo, a Floresta Amazônica

(A) perdeu mais de 50% da cobertura vegetal na área localizada no Brasil.

(B) tem apresentado uma desaceleração contínua, porém insuficiente, no ritmo de desmatamento.

(C) teve uma redução de cerca de 15% da extensão que tinha nos anos 1970.

(D) perdeu 30% de sua área desde 2019 devido a queimadas e incêndios.

(E) enfrentou o mais longo período de queimadas e incêndios em 2010.

Resposta:

Alternativa Correta: C) teve uma redução de cerca de 15% da extensão que tinha nos anos 1970.
