Global deforestation of tropical rainforests begins to decline. After a peak of 300 million hectares per year, it rapidly declines to 100 million hectares per year (pre-industrial levels of the 18th century). Deforestation of temperate rainforests was already declining sharply, from over 400 million hectares per year in 1625 to 20 million hectares per year in 1970, and to zero in 2000.
