Before 1788, kangaroo was a popular meat in Australia. Then the Europeans arrived with their sheep and cattle and dramatically impacted local cuisine and landscape.
Cows and sheep, with their cloven hoofs, cause erosion and damage the fragile Australian ecosystem. But kangaroo, having evolved with the landscape, have soft feet that don't degrade the fragile rangeland.
There's one more reason why kangaroo are less damaging to the ecosystem, they don't produce methane. They have special bacteria in their stomach lining, so unlike cows and sheep which emit an estimated 14% of Australia's greenhouse gasses, kangaroo can digest without emitting any methane.
In this video, we talk to Australian chef Jean Paul Bruteneau who helped advocate to change the laws to allow kangaroo to be eaten by humans in New South Wales (In 1993, it became legal in the entire country in 1993).
