Yes, CarolC, the mass slaughter of a native species in it's native habitat can be barbaric. I give you, for example, the American Buffalo (Bison bison) and the river otter.

When people raise and harvest a species of animal, the captive population rises and fall independant of the native one.

The captive herds of animals are raised, fed and owned by their owners. The native ones belong to all of us.
