http://www.polarbearsinternational.org/our-work/community-outreach/save-our-sea-ice, "as the Arctic continues to warm due to climate change, two-thirds of the world's polar bears could disappear by mid-century—although hope remains if action is taken to greatly reduce greenhouse gas emissions." The world's largest predators are no match for intensity of the melting sea ice. It's up to us to do our part. The organization urges people to take the challenge -- do little things, put on a sweater rather than upping the thermostat; turn out the lights when you leave a room. What other things can you do? How about
- Planting a tree (or two or three)
- Walking or biking rather than hopping in the car; for longer trips, catch the bus
- Unplug power cords
