Tropical rainforests around the world are reviving

Tropical rainforests around the world are resurrecting, but young trees may not be as resilient as many wild animals or keep plenty of carbon dioxide causing global warming like old trees, scientists say.

The debate about tropical rainforests has been going on for decades and, more recently, has become the subject of a stir among conservation scientists. It was the main theme of a symposium recently held at the Smithsonian National Museum of Natural History in Washington, USA.

About 135,000 square miles (about 350,000 square kilometers) of the deforested primary forest are revitalizing, according to Greg Asner, of the Carnegie Institute based in Washington, who presented at the symposium. That number accounts for a quarter of seven percent of primary forest.

This regeneration is relatively fast, the forest canopy covers only after 15 years when the tree is taller and denser, providing a habitat for the organisms to adapt to the environment .

These scientists argue that the future of tropical forests may not be as fragile as other conservation experts warn, mainly because humans have lived in forests or lived near tropical forests are gradually moving away. elsewhere, mostly to cities, making plants grow.
