Abstract:

The renewable resources exhibit a significant rate of growth or renewal. Therefore, they would seem good candidates for sustainable harvest. The definition of sustainability is problematic.
This is particularly the case if we admit that the rate of growth or renewal for a resource fluctuates
through time. Indeed, the process of evolution raises some fundamental questions about the feasibility of sustainable resource use. The first part of this article contains the resource dynamics. The second part describes in more detail the impact of the environmental policy and implementation of the optimum.
