Many other response teams with CERT in their name have sprung up and are part of the Forum of Incident Response and Security Teams (FIRST), of which CERT/CC was a founding member. They all work independently toward a common goal of computer security.
When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.
Though they are excellent swimmers, polar bears spend most of their time atop Arctic sea ice. Sea ice is an ecosystem in itself, supported at its base by plankton and algae at the bottom of the food chain. Polar bears share this habitat with seals, whales, Arctic foxes, birds and even people.
