Heard an interesting point about that, which made me think a little.
It's pretty long winded, but the gist of it is that these reserves breed native wild animals and in a lot of cases prevent them from going extinct. The meat is apparently distributed amongst local African communities and the money that such hunters spent on being able to hunt the older animal is put back into these reserves so the cycle can keep going.
So by paying to shoot the lion she, in effect, did a lot of good for international conservation.
That's a very rough and brief explanation.
But got me thinking.
Even so, it was pretty stupid of her to post such a picture so publically...people were always going to react the way they did (I was outraged too)
