Remember the doomed, cane-toad-eating crocodiles? Well they’re still eating, and dying: A new report suggests that as much as 77 percent of the crocodile population along the Victoria River has now perished from toad poisoning.
In yet another example of the “solution to one problem becomes an even bigger problem” doctrine, cane toads were purposely introduced to the region as a pest-control measure for beetles in the sugar cane fields. But sure enough, the toads soon became pests themselves, to the point where volunteer groups are trying to stop the toads’ spread across the continent.
One community has been promoting “cane toad golf”—basically whacking the toads with golf clubs. A more humane way, experts suggest, is to put the toads in the fridge until they’re numb and then transfer them to the freezer to kill them.

Hungry for a kanga-burger? Replacing beef and mutton with kangaroo meat could significantly cut down on ruminant livestock emissions, according to a new report commissioned by the Australian government. Bovine belching is a massive source of methane emissions. But while a single cow can produce 300 to 500 liters of methane gas per day— enough to inflate 80 party balloons—kangaroos produce almost none. In other words, if cattle were Hummers, kangaroos would be Priuses.
As we’ve reported previously, Australian scientists have tried to fix the problem by transferring digestive bacteria from kangaroos into the guts of livestock. But this new report suggests that switching right to kangaroo meat could be a better move.
A potential model cited by the report would replace 7 million sheep and 36 million cattle with 175 million kangaroos by 2020, allowing Australia to cut about 16 megatons of carbon emissions every year. As the price of emission permits increases, kangaroo harvesting would become a lot cheaper than livestock farming. Kangaroos are hardier than livestock, and could better handle the effects of climate change like decreased water supply. They would be the ideal free range animal and yield meat that is high in protein and low in fat.
Still, there’s the 175 million kangaroo question: Will anyone eat it?
