Passage Summary: While most experts want to ban ivory to save elephants from poachers, Zimbabwe argues they shouldn't be punished because they manage their elephants well and need the money.

Conclusion: Zimbabwe opposes a total ban on the ivory trade despite the general threat of elephant extinction.

Reasoning: Zimbabwe has successfully managed its own poaching issues and relies on the revenue from controlled culling to manage its herds.

Analysis: To find the underlying principle, we need a rule that justifies Zimbabwe's specific objection. The conflict is between a global solution (the ban) and a local success story (Zimbabwe's conservation). Look for a principle that suggests a country should not be forced to adopt restrictive measures if it has already solved the problem those measures are intended to fix. The ideal answer will bridge the gap between 'other countries have a poaching problem' and 'Zimbabwe should be allowed to trade.'
