Assertion:. All environmental, financial and human resources must be used keeping in mind both the present as well as the future.
Reasoning: The misuse of any of these resources will lead to fewer opportunities for future generations

Assertion (A) is not true but Reasoning (R) is correct.

All environmental, financial and human resources must be used keeping in mind the future.

Sustainability means continuity in the availability of opportunities. To have sustainable human development, each generation must have the same opportunities. All environmental, financial and human resources must be used keeping in mind the future. Misuse of any of these resources will lead to fewer opportunities for future generations. For e.g. If a community does not stress the importance of sending its girl children to school, many opportunities will be lost to these young women when they grow up. Their career choices will be severely curtailed and this would affect other aspects of their lives. So each generation must ensure the availability of choices and opportunities to its future generations.
