Do you remember what problems they may have in the future?

Yes. If hunters catch a giant panda, they will kill it for its fur.

If farmers cut down trees and forests, giant pandas will have nowhere to live.

If people find baby pandas alone, they will often take them away.

Please remember:

If we do nothing, there will be no giant pandas in the world.

We can also say:

There will be no giant pandas in the world if we do nothing.
