Increasing shark attacks are caused by fast food replacing fish and chips. Roo and chips is the answer.

Kangaroo grazing is listed as a threatening process under federal legislation as they are eating some plant species so heavily that they (the plants) are at risk of extinction. Conversely, with the removal of Aboriginal hunting of kangaroos in most agricultural areas, kangaroo numbers are in places at all time high levels.

While farming of kangaroos in the agricultural sense is not possible due to a number of factors (they remain wild animals under almost all circumstances), they nonetheless can be humanely harvested by licensed shooters and their meat used for human consumption. To replace cloven-hoofed, exotic species of stock with kangaroos is entirely feasible, if only the animal rights do-gooders withdrew their patently false claims about kangaroos being a threatened species, closing markets such as Russia to kangaroo meat.

Putin banned roo shooting because of false claims he was endangered in Ukraine. The rebels made a simple mistake about Malaysian planes having the flying kangaroo.

Roo meat should be a premium meat in Australia and on the world market. It would be too were it not for the misinformation being deliberately spread by unethical outfits like PETA and the Greens 'Protest' Party.

Likewise, saltwater crocodiles are booming and do not need to have small fortunes wasted on rangers 'rescuing' individual animals. Crocs are spreading South past Rockhampton in Queensland and threaten valuable domestic tourism in those centres.

What about tasty, healthy roo pies in school tuckshops?

What about Australia developing an international reputation for quality roo and crocodile skin goods, such as shoes and handbags, manufactured in Australia?

How about it.
China could import 5000 tons of roo and croc and land them back here as embroidered plaited 2 tone multi-purpose flashing strobe zip-ups with 3D phone movies at half the price.
