When an architect or a town planner plans, he is in actuality, intervening with ‘living system’. The intervention can be disastrous if insufficient thought is given to the effects of development, especially its long-term consequences on the environment. The blend between man and nature will not be harmonius, but there will be imbalance or contradiction instead. In the long-run the total environment is bound to deteriorate. This is what ecology is all about- the inter-relationship between living and non-living things and their habitat.
