Evolutionary biologist, entrepreneur, urban renewal expert, and conservationist share stories about bringing new life to abandoned places. Topics include genetic adaptation of wolves in Chernobyl, rapid evolution in African elephants, benefits of circular cities, rebuilding Detroit one lot at a time, and tracking bears for coexistence.
Non-lethal tools such as GPS tracking and bear-resistant bins are being developed to reduce negative encounters between polar bears and humans, but the ultimate solution lies in reducing carbon emissions and addressing climate change.
Detroit Future City is transforming abandoned lots in the city into green spaces and sustainable gardens, improving neighborhood aesthetics and promoting biodiversity, climate resilience, and community.

The impact of climate change on polar bears
Polar bears are facing habitat loss due to climate change, as melting terrain and ice leave them stuck on land for longer periods. This leads to hunger and a search for food, often resulting in conflicts with humans. To mitigate this, non-lethal tools are being developed, such as GPS tracking and bear-resistant bins, to reduce negative encounters between polar bears and humans. However, the ultimate solution lies in reducing carbon emissions and addressing climate change.
Revitalizing abandoned lots in Detroit
Detroit has faced a significant decline in population, resulting in numerous abandoned lots in the city. To address this, the organization Detroit Future City is implementing a resilient neighborhood model, transforming vacant lots into green spaces and sustainable gardens. This approach not only improves the aesthetics of the neighborhoods but also supports climate resilience by promoting biodiversity, managing stormwater runoff, and creating a sense of community.
The challenges of coexisting with polar bears
As polar bears face habitat loss, they are venturing closer to human settlements in search of food. This poses a safety concern for both humans and bears. To ensure coexistence, communities like Churchill, Manitoba, have implemented strategies such as indoor garbage disposal and bear-resistant bins to prevent human-bear conflicts. Additionally, efforts are underway to develop innovative approaches, like using temporary fur tags, to track and safely relocate polar bears that come too close to human populations.
Protecting polar bears through education and action
Conservationist efforts are focused on raising awareness and educating individuals about the importance of understanding and respecting polar bears. Alongside education, reducing carbon emissions and transitioning to cleaner energy sources is crucial in preserving the Arctic habitat of polar bears and mitigating the impacts of climate change. By taking collective action, we can create a safer and sustainable future for both polar bears and humans.
Lots left vacant, offices full of equipment but devoid of people, entire villages literally left to the wolves--this hour, TED speakers share stories about bringing new life to abandoned places. Guests include evolutionary biologist Shane Campbell-Staton, entrepreneur Garry Cooper, urban renewal expert Anika Goss, and conservationist Alysa McCall.
