Therefore, reducing deforestation is usually more beneficial for climate change mitigation than is reforestation. [7] Many countries carry out reforestation programs.
The bark of willow trees contains salicylic acid, the active metabolite of aspirin, and has been used for millennia to relieve pain and reduce fever.

Although about 80 percent of humans' food supply comes from just 20 kinds of plants, [155] humans use at least 40,000 species. [156] Earth's surviving biodiversity provides resources for increasing the range of food and other products suitable for human use, although the present extinction rate shrinks that potential.
