Thanks for posting this Observe. TED Talks have a great reputation, especially, I would suggest, among those who are against our sport, or at least sceptical about it. This is a very useful reference to refer people to.
Unfortunately, I believe that in a a few years, we will be able to say the same thing about Elephants and just about every other large mammal in Botswana. Same as Kenya. A shame more people can't be at least marginally rational.
