Killing Koalas

On Kangaroo Island off the coast of Australia, they have a problem... there are too many koalas... they are eating all the foliage, the trees are dying and the koalas may eventually die of starvation because there's no food left for them to eat. They've tried sterilizing the koalas, and even transporting large quantities back to the mainland, but to no avail, they apparently think they're bunnies. Anyhow, conservationists are asking the government to "thin the herd", if you will, but they're afraid to because of the tourist backlash. I have the perfect solution... give away koalas to each tourist who visits. Seems like a plan to me.
