Australia plans to cull over 10,000 wild horses, but scientists say it's not enough

The horse cull plan "stinks". Why not allow Evolution to function? What not try birth control means? So these beautiful, stately, graceful horses will wind up as pet food, carrion, or human food for the benefit of those people/countries with Neanderthal taste indifference? People caused the ecological problem and now resort to death to get a resolution? Phooey! I can think of many overpopulated human groups, yet no one suggests culling those?
