Q. Discuss why it has been pertinently said that “forests precede mankind; deserts follow”. (6marks) (2019)
-> The chapter ‘Ailing Planet: the Green Movement’s Role’ by Nani Palkhiwala is an enlightening treatise on environment degradation, the causes behind, and the solutions needed to be implemented to save our ailing planet. The line from the chapter ‘Forests precede mankind deserts follow’ has been written to bring people’s attention to the fact how crucial trees are for mankind. This line means before God put man on earth, he put trees on it to create wholesome and hospitable conditions for him and his posterities; however, man in his recklessness destroys trees and makes lands barren like deserts; in such conditions mankind also disappears. To sum up, the line means trees are indispensable for mankind to survive; in their absence, mankind will dwindle away.
