We have to confess to not knowing that: a) there are 1.2 million feral camels in Australia and that the population is expected to reach 2 million by 2020; and b) that they are major contributors to the emission of greenhouse gases.
Apparently, a camel produces an estimated 100 pounds of methane a year, which is about the same as 1.1 ton of carbon dioxide in terms of the greenhouse gas emissions. In addition, the report says, they are trampling and eating all sorts of vegetation.
As for why there are so many camels in Australia, the AP says they were "introduced in the 1840s to help explorers and pioneers travel through Australia's arid interior." Australia now has more camels than any other country in the world, AP adds.
And what does the report suggest be done? Sharpshooters, AP says, "could earn so-called carbon credits for slaughtering camels. Industrial polluters around the world then could buy the credits to offset their own carbon emissions."
