TUTORIAL 1

LDC: With the term LDC (Less Developed Countries) we mean the countries which don’t have a highly organized political system and economy and constrained resources to solve their environmental problems and we concentrated mostly in countries from Africa South America and Asia.

GREENHOUSE GAS: Greenhouse gas is any of gases that are going to contribute to the highly rise in temperature of the earths atmosphere the last decade for example carbon dioxide which causes serious problems generally in the earth such as the slowly melt of the icebergs in Antarctic which in future will cause serious and undesirable problems for humanity.

iii) We find out in our calculations that the population of the earth at the year 2050 will be approximately 9, 4 billions people, with that calculation we agree with UN because they support that the population will be on the same numbers. In the year 2100 UN gives that the population of earth will be 7 billions in our calculations we found about 14, 7 billions. That shows that finally the growth rate will stop and will finally start to decline. Finally we predict that the growth rate is stable contact.
