Hundreds of thousands of elephants used to roam Asia, but now there are only about 16,000 left.
A group of elephant conservationists got together in the Sri Lankan capital, Colombo, on Friday to discuss the problem.
Because the elephants' natural home is being destroyed, they are forced to wander into farms and villages to look for food, and they end up damaging crops.
Sri Lanka has another problem for the elephants too.
A civil war there has disturbed about 300 wild elephants, making them wander into villages even more than before, which is making the problem worse.
