How do you stop black leopards being endangered?

First, let's look at the question. The black leopard is a color phase of the leopard, not a separate species. They are more common in Asia than Africa. Both black and normal colored cubs can, and usually do, occur in the same litter. In Africa, less than five per cent of leopards are black, but in Asia, nearly twelve per cent are.As a species, leopards are not endangered.But some races are in trouble.
