Question

Y r the equatorial regions called the lungs of the world

Answer 1

Tropical rainforests are often called the "lungs of the planet" because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate. In a paper published online Feb 6 2013 by the journal Nature, a team of climate scientists from the University of Exeter, the Met Office-Hadley Centre and the NERC Centre for Ecology & Hydrology, has shown that these variations reveal how vulnerable the rainforest is to climate change.

Answer 2

The equatorial region because of the presence of the dense Tropical Rainforest is called the 'Lungs of the world'. This is because the rainforests function as a giant machine that absorb a large amount of carbon dioxide and produce oxygen
