The disappearance of the deer from the forest indicates the EXTINCTION OF THE DEER.
The extinction of the deer from the forest will throw the ecosystem out of balance and has negative impacts on the ecosystem. After all the deer has been eliminated, the elephants too will either have to find another source of food or be wiped out.
