2f+10=36 Each friend gets two candy bars (2f) and there are 10 spare bars (10). If the total is 36, then he can only treat 13 friends.
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.
