Sustainable activity
sustainable development is “development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Examples are as follows:
sustaining the potential of natural and physical resources (excluding minerals) to meet the reasonably foreseeable needs of future generations; and
safeguarding the life-supporting capacity of air, water, soil, and ecosystems; and
avoiding, remedying, or mitigating any adverse effects of activities on the environment
Basically farming & fishing do not compromise the ability of future generations to meet their own needs. But mining a minerals (which have a limited supply) will compromise future generations.
