The statement is justified because:
(i) Exploitation of resources by greedy and powerful people lead to a massive depletion of resource and deprives the weak and future generation.
(ii) There is an unequal distribution of resources in every state, leading to excessive development in some areas and severe lack in others. Even the society has been divided on the basis of economy and facilities available.
(iii) Unplanned and unchecked use of resources has also resulted in problems which are shared by all the countries of the world. This includes environmental degradation, global warming, pollution, depletion of the ozone layer, etc.
