Answer:

Nearly 50%

These forests are being cut down for various purposes, such as construction of urban areas, construction of wooden houses, making furniture, overgrazing of animals, forest fire. It causes both naturally as well as due to anthropogenic activities.

Thus, nearly 50% of the forest is reduced in the last 8000 years.
