The life of a koala is rough. They have trouble finding food. And contrary to popular belief, they have predators. Kangaroos are the major predator. In my twenty plus years studying them, a day has not gone by when I haven't seen kangaroos harassing the koalas. On a good day, the kangaroos will simply stand below the koala, bouncing like a child on a pogo stick. But on the bad days, I've had to intervene in their disputes many times. Needless to say, I've been punched by a kangaroo many times.
What's more, the koalas don't seem to like Australia. According to the surveys they've filled out, they are not fans of the Australian outback. Specifically, koalas are tired of eucalyptus and are also not fans of the Australian accent. Kuehlenschrank said, "They much prefer the German and Austrian accents."
All of this leads to a crippling koala depression. The symptoms are easy to spot. Excessive sleeping. Sluggishness when awake. The inability to complete simple tasks, even as simple as raising one's head. Suicide is prevalent. Kuehlenschrank explains, "Suicide opportunities surround them. All they have to do is let go and they'll fall out the tree to the waiting kangaroo." And even if the koalas are taken out of the trees, there is still a great risk.
Kuehlenschrank explained, "Taking the koalas out of a threatening environment is nearly impossible, as koala claws are razor sharp. These claws are the "perfect" suicide method."
