Conclusion

- General public is poorly informed

- Misinformed?

- Doomsday prophets overshadow real efforts

- Nunavut has dedicated co-management partners

-> balancing system

- Adaptive system through IQ and science


39/45

39

Conclusion - continued

- Intense research and monitoring program

- Effective conservation and management system

-> more polar bears now than historically

- Begs the question: how many bears are enough?

- Best harvest monitoring system

-> example to other jurisdictions

- We further developed non-invasive techniques

- We will continue to manage our bears responsibly

-> Nunavummiut, Canadians, world-citizens
