Resources are indiscriminately used to satisfy the greed of a few, leading to their accumulation in few hands, dividing society into rich and poor. This causes global ecological crises like global warming and environmental pollution. Therefore, equitable distribution ensures all people have access to resources, maintaining sustained quality of life and global peace.

The answer must link two ideas: (1) unequal/indiscriminate use of resources causes socio-economic and environmental problems, and (2) equitable distribution is the solution for sustained quality of life and global peace. Both points are directly from the textbook passage. Examiners expect you to mention consequences of unequal distribution (rich-poor divide, ecological crises) and then justify why equitable distribution is necessary.
