A study using satellites and aerial photography conducted by the United Nations, warns that the environment has worsened so badly that it's 'critical' in many of the eighty-eight countries investigated. A recent report of our parliament's Estimates Committee has highlighted the near disastrous exhaustion of India's forests over the last four decades. India, according to reliable data, is losing its forest at the rate of 3.7 million acres a year. Large areas, officially designated as forestland, "are already virtually treeless". The actual loss of forests is estimated to be about eight times the speed indicated by government statistics. The world's ancient patrimony of tropical forests is now eroding at the speed of forty to fifty million acres a year, and therefore the growing use of dung for burning deprives the soil of a crucial natural fertilizer. The world bank estimates that a five fold increase in the rate of forest planting is needed to cope with the expected fuel wood demand.
