About one-quarter of the Earth 's land, excluding the polar regions, is covered by forests. Every year, deforestation reduces forest cover significantly. scientists at the University of Michigan estimate that half of the Earth 's forest ecosystems have already been destroyed. Deforestation not only contributes to changes in the climate, it also causes local changes in the weather. Trees transpire, or release water into the atmosphere, during photosynthesis. This water replenishes clouds and maintains rainfall. Without this transpiration of trees, deforested areas become much drier. According to an article, “Changes in weather and shelter cause deforested areas to undergo a tremendous loss of biodiversity, which has global consequences when forests harbor unique species. Scientists have not yet tested even 1 percent of the plants in tropical rainforests for medicinal use, but they regularly discover species useful to people. However, some of these forests and their potential benefits may disappear by the end of the 21st century.” (Cairoli) That same article went on to state that deforestation is a threat to the human food supply in several
