In many regions (1) of the tropical rainforest, pollution/conservation (2) is urgently needed.
People there are destroying far too many trees. Sometimes they do this for fuel/fun (3) to heat and cook with.
Sometimes the wood is sold, and expensive furniture in the is made/broken (4) of it.
But often, thousands of acres of precious forest are simply burned to give poor farmers land to plant/cook (5) and eat/grow (6) their crop.
This land is only fertile/frozen (7) for a few years however, and gives the farmers only two or three meals/harvest (8).
The consequences for the earth's climate/diameter (9) are extremely dangerous.
Heavenly/Global (10) warming can cause the glaciers to freeze/melt (11), with serious flooding in some parts of the world, and dry land and desserts/deserts (12) in other places.
Destroying the earth's rain forests upsets the earth's ecological/economical (13) balance.
