I have an idea that may seem odd but I think it would help our environment and preserve native species.
It involves being able to eat kangaroos. Why? Because currently they're protected and toi can't even eat them if they're roadkill. This is a waste of nourriture and encourages carrion eaters to hang around roads and risk harm from cars as well (raptors, owls, ravens, magpies, snakes)
Their numbers are way out of control in quite a few country areas and cause car accidents and have even been known to attack people (though rarely).
If we could have farming of these animals, without fencing them in....
