Right now, our mother -- our mother -- all of our mothers, Mother Earth is hurting. And she needs a generation of thoughtful, caring and active kids like all of you to protect her for the future. You can help us win the battle to clean up our air, our water, our land, to protect our forests, our oceans and our wildlife.

It's interesting in this day and age to do a film about political espionage and wiretapping. I don't think that those types of secrets that J. Edgar Hoover was able to obtain and keep for such a long period of time would be possible in today's world, with the Internet and WikiLeaks.

If you can unify the public mind saving an iconic species like the tiger, like they did with the panda, that means you have to protect their habitat and everything that they hunt.
