Answer :
The word that means the opposite of "enable" is "prevent."
Here's why:
1. **Enable** means to make something possible or allow it to happen.
2. **Prevent**, on the other hand, means to stop something from happening or to keep it from occurring.
So, in the context of improving the world, enabling something would involve making it happen or allowing it to occur, while preventing something would involve stopping it or keeping it from happening.
