If oil supplies get exhausted, this will affect our life-style significantly because in such a situation the machines, vehicles, railways etc” could not be run. People would not be able to go from one place to another as they can go now. Many of our activities depend on petroleum products like petrol, diesel, LPG, CNG etc. People may be confined to smaller places as was in the ancient world’ However, as the scientists are doing research to find out alternative source of energy, it is hoped that they would be successful in their efforts. They may be able to use solar or wind energy in place of petroleum products and in that case. if the oil supplies get exhausted, it would not make any difference in our lives. Perhaps, life would become better in future.
Technical and economic development has led to more consumption of resources. Higher level of technological development needs more and more resources for production activities.

Technical and economic development has led to more consumption of resources. Higher level of technological development needs more and more resources for production activities. Gandhiji placed the exploitative nature of modern technology as the root cause for resource depletion at the global level. He was against mass production and wanted to replace it with the production by the
masses. It was the higher level of technological development of the colonial countries that was responsible for the over exploitation on of resources of the colonies. Similarly, economic development depends on more consumption of resources. For example, water resources are being over exploited to expand irrigated area and dry-season agriculture.
