Deforestation

Deforestation is cutting or burning trees. Most deforestation happens because people need lands for farming. In poor countries, most people must plant vegetables. Farming is the main resource for living.

Economy is the main reason of deforestation. Poorer countries use their only resources for money. People use land for farming to make money because of poverty. Governments cut trees because of their debts and development of industries.

But these solutions can cause even worse problems. Trees are made of about 50% carbon, so when trees are burnt, carbon is released into the atmosphere. Cutting them down reduces the amount of rain, raising temperatures. The sun heats the land and dry it out. Also it is very harmful for the animals and plants that live in the rainforests. Tropical rainforests hold about 50% of earth's species of animal. When we bum forests, we Kill the animals too.

The solutions to problems such as deforestation must be found urgently. And. if deforestation continues, in just 100 years there will be no more rainforests left.
