2.

Why are tuskless elephants occuring more than they have in the past?

Tuskless elephants survive to pass on their tuskless genes to their offspring.

Elephants can induce the loss of tusks after severe instances of stress.

Elephants with tusks are hunted and killed, so we don't see them in the wild.
