If we focused clearly on the modifications of the percentages that happend during 25 years we can classify those data to three categories :
Firstly we can speak about New Zealand and Chile’s percentage of forest areas, those two countries have nearly Tha same percentage of the increase of forest areas although their forest land percentage coutrary to the country area is different which is 28.8 in New Zealand on 1990 and 20.4 in Chile in the same time, their forest percentages keeps I creasing at the same ratio to will reach 32.3 in New Zealand on 2015 and to be 22 in Chile.
Australia has different character on its situation, its forest percentage is decreasing which is came down from 21.9 on 1990 to will be 20 on 2015.
Finally for Brazil the sutuatio is more worse, its forest percentage compared to the country land area is readicing and that losing of forest land is including a big surfaces, recording a high mines ratio which it will be 53.5 on 2015 when it was 57.2 on 2005 and 62.2 on 1990.
From those three categories we can conclus that some policy countries about the green plces and forest areas are making seccess even if thier land not that green some of them having deserts and hard weather like New Zealand, but they improve their land. When other countries like Brazil, who conciderd the lung of the world it losing every year those trees and its value and that will affect badly all the world not only its country.
