I find it disturbing that lions have been on (or close to, I don't know where they are now) the endangered species list, and I've vowed that when I become a rich physisist, I'm going to donate a huge some of money (and hopefully time) to causes like this one. It's a great thing to see these people helping out the lions!
I own a book that's a spinoff of that. It's another really big book of Great Cats with a LOT of lion info, which is good!
