Hirohava,
No I am not joking about the ivory. Before you get excited you may want to consider these facts:
1) There are more elephants in Africa than there are elk in North America.
2) Zimbabwe has ~80,000 resident elephants with another 15,000 transitory jumbos that travel between Botswana and Zimbabwe. Of these 15,000 animals the government allocates 1% for sport hunting. This brings in over $8 million US a year, much of which goes directly to the various tribes whose communal lands have the hunting concessions and to conservation programs to help maintain and enhance the elephant, lion, cheeta, and black rhino populations.
3) African countries where sport hunting has been totally banned have seen the worst decline in elephant populations due to poaching by the various tribes and lack of funding for game management and enforcement.
In any event, more elephants have to be killed due to human/elephant conflicts than due to the 150 or so that are taken by sport hunters.
Sorry for the soapbox, but it is frustrating to encounter so many people who have been mislead by animal rights groups without considering the data.
