It is the complete clearance offorested land. "his is done for

various reasons, which wewill look at later.

' rail has some of the fastest clearing forestareas within the world. *atellite images show thatover +fires can be burning at any one time in

the area. "here are three main reasons thatdeforestation takes place, they can be bracketedinto the following-

' Government Policies# aimed at helping localpeople develop the economic side of life in thearea.

' TNC (Transnational Companies)# these wish

to make money from the natural resources thatare in the area

' Local People# "hey may need to the land to live

on or grow crops on in order to survive. lmost million people live in the rainforest.

Once the rainforest is destroyed it is unlikely to ever be replaced.

* The native A)a+on $ndians used a )ethod of far)in,

called$slash and burn%(here they deforested an area

and used it for far)in, for a fe( years. They then left it

and (ent on to another site.

* Plants and trees -uickly invaded the deforested area so

that soon there (as very little evidence that they had

ever been there.

* #lash and burn re-uires a lot of land since far)ers )ust

)ove their crops to ne( fields every fe( years.
