Question

The amazon rainforest are called
A. Heart of the planet
B. Lungs of the planet
C. Liver of the planet
D. Kidney of the planet

Answer 1

Hint: It is the largest and most diverse tropical rainforest on Earth which covers a staggering 5.5m square kilometres. The trees within its stretch have the ability to draw in carbon dioxide and breathe out oxygen – just like the human lung.

Complete answer:
The Amazon rainforest is the most biodiverse region on earth. It provides shelter to three million species of plants and animals. Billions of trees absorb tons of carbon dioxide every year and slow down the climate change along with producing 20% of earth’s oxygen, hence they are also known as ‘Lungs of Earth. Around 30% of the world’s primary forests are housed in the Amazon basin, which accounts for roughly 90 to 140b tonnes of CO2 being taken out of the atmosphere yearly.

It has been claimed that about 99% of Amazon fires start from human actions, either on purpose or by accident. It has also been mentioned by international bodies that fires have been set up to clear the land for cattle ranching, farming, and logging. The number of human-made fires is growing rapidly which has literally plagued the Amazon in recent years and also disturbed the ecosystem drastically.

Hence, the correct answer is option (B)

Note: Not just animals living on land, animals surviving underwater might also be affected due to change in water chemistry. There are certain species, who use land as well as water both for their survival, these species also bear the risk of getting killed by fire.
