Answer:
At present, the populations of richer and more developed countries do not destroy more forests than those of less developed countries, because thanks to their economic development they do not need new areas to exploit and, therefore, they conserve their natural areas without major modifications.
The poorer countries, on the other hand, use their natural resources as an economic asset, thereby greatly modifying their natural environment to meet their economic needs.

1) heat from radioactive decay in the core of the Earth heard the mantle. 
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started. 
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.
