Deep dives
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.
