Why cutting down the rainforest is bad?
When these forests are cut down, the plants and animals that live in the forests are destroyed, and some species are at risk of being made extinct. Further, as the large-scale harvesting of lumber from the rain forests continues, the balance of the earth’s eco-system is disrupted.
Who is causing deforestation?
The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.
Why can’t we afford to lose the Amazon rainforest?
The existing forest is absorbing some carbon dioxide already. In terms of the global carbon cycle, tropical forests have a carbon sink roughly equal to half of what is in the atmosphere. About half of that is in the Amazon. This means to lose the Amazon would dramatically increase climate change.
Where is the heart of the earth?
Antarctica
Antarctica is the sixth continent, but it’s a continent that you can define as the heart of Earth. The world’s main marine current is the circumpolar Antarctic current that moves from west to east around Antarctica.
How are trees cut down in the rainforest?
They cut large trees like teak; mahogany for making furniture and the smaller one is used to produce the charcoal. The trees with quality wood are used to obtain timber and other is for wood chipping. Rainforest are cut down for growing fruits, cereals, pulses. The area in tropical countries where all these things are grown was once a rainforest.
Why do we need to get rid of the rainforest?
Developed nations relentlessly demand minerals and metals such as oil, aluminium, copper, gold and diamonds, which are often found in the ground below rainforests. The forest therefore has to be removed in order to extract them.
How long will it take for the Amazon rainforest to be destroyed?
We are destroying rainforests so quickly they may be gone in 100 years. At current rates of deforestation, rainforests will vanish altogether in a century. Stopping climate change will remain an elusive goal unless poor nations are helped to preserve them.
Why are so many rainforests being destroyed in Central America?
Cattle ranching. Many rainforests in Central and South America have been burnt down to make way for cattle farming, which supplies beef to the rest of the world. It is estimated that for each pound of beef produced, 200 square feet of rainforest are destroyed.

How is deforestation related to the Amazon rainforest?
Trees have been cleared from a large area in the Amazon rainforest of South America. Deforestation is the clearing, or cutting down, of forests. The word is normally used to describe the actions of humans in removing forests from the planet, rather than destruction caused by such natural events as hurricanes.
Why do people cut down trees to grow crops?
In some countries, especially in tropical areas and in Southeast Asia, farmers cut down large trees and then set fire to areas of a forest to kill off all the animals and plants living there. The ash from the fire helps to fertilize the land, and crops can be grown for a few years before the land becomes useless.
