Why should man not cut jungle for his need?

Answer 1

Animals are killed, less trees means less oxygen producers.

Jungle is a fragile ecosystem. For example , if cows eat grass and the grass if suddenly destroyed, the cows will starve.

Also , the jungle is home to indigenous creatures that could be endangered or driven to extinction if their habitat ( the jungle) is destroyed.

Man should find areas without jungle and use sustainable farming methods to harvest wood.

Answer 2

Forest have several jobs on the earth:

They provide oxygen for animals like us to breathe
They protect the surface of the earth from the sun, heavy rain, snow, wind etc
They provide habitats for many organisms
