Which concept does the graph below illustrate? a. deforestation b. desertification c. the decrease of tree heights over time d. the increase of young trees over time

Correct A. deforestation
Opening the link on the internet, it opens up a graph that illustrates the estimated area of rainforest in millions of acres. The trees are equivalent to bars that level the area that there is in the years shown above those trees - in 1950 it was estimated to exist just below 2400 millions of acres, and in the year 2000 it was estimated to exist about 1500 millions of acres. This is what is expected when there is deforestation. Deforestation is the destruction of a forest, or parts of it, whether to use its resources or not, that does not grow back again.

D. the increase of young trees over time
