This is a cute video that skimps maybe a little too much on detail when it comes to explaining what the scientific terms mean, but it does do a great job of relaying the importance of polar bears to their ecosystem and some easy ways we can help them out. I don't have the book they reference at the end, but I would assume it goes into a little more details that were lacking in the video. Either way, it's good, shot and I think your and your kids will enjoy it.
