Also question is, why are forests decreasing?

Urbanization. As the population grows, the needs of people increases which further leads to deforestation. Forests shrink to a great extent to meet the requirements like for construction of roads, development of houses, mineral exploitation and expansion of industries.

Similarly, is forest cover increasing or decreasing? There has been a growing consensus in recent years that because humans cut down so many trees (most particularly in the rainforests) that global tree cover is shrinking.
