The development commission argues for greater development and that Figoria has the right to govern its own resources. These points would be weakened, not strengthened, by this principle.

The development committee thinks development should go ahead for economic reasons. Affirming the environmental rights of future generations would only weaken the argument.

This tells us that if development has not yet been proven harmful to wildlife, development should go ahead. That’s exactly what the development committee assumes, so affirming it strengthens their argument.

This undermines the development committee's assumption that Figoria's past conversation gives it the license to develop as other countries have done. That means that this only weakens.

The development committee is arguing for greater use of natural resources through development. The claim that this course of action is imprudent directly undermines the argument.
