Tropical rainforests have significantly changed overtime by the tremendous act of deforestation. About 64% of the world's tropical rainforests have been destroyed from this act. This was proven on a website when it states the following: "in North America, about half of the forests in the eastern part of the continent were cut down from the 1600s to the 1870s for timber and agriculture." This also results in only 36% of tropical rainforests remaining unimpaired. An enhanced and more positive alternative to deforestation is reforestation. Reforestation is the procedure of replanting trees in regions that have been greatly affected by natural disasters such as fires and droughts. Chopping down trees in particular areas at a time allows a few areas to be utilised for agricultural purposes whilst other areas can regrow.
Reforestation can change the future outlook for tropical rainforests. It is estimated that within 100 years, the world's tropical rainforests will vanish if the human alteration of deforestation continues. However, reforestation will prevent this traumatic event from occurring as it will allow this particular biome and its flora to nourish and regrow. An example of reforestation helping this biome is the Amazon Rainforest. Almost 30, 000 hectares of this rainforest have been reforested. This action has had a positive impact on the environment as it created jobs for the surrounding communities and assisted in restoring biotic ecosystems.
