World Changing Conversations

Today I had my first private lesson at inlingua, with a Level 2 student from Mexico.  We are focusing on conversational skills, so as a speaking topic, I posed this question:

If you could change something about the world, what would it be?

Here's the kicker, though... it has to be reasonably realistic.  You can't say "I would turn Donald Trump into a flea (a harmless little flea), put that flea in a box, put that box inside of another box, mail that box to myself, and when it arrives I'll SMASH IT WITH A HAMMER!"  As much as that would greatly improve the world, it's unfortunately not realistic.

The question is honest: what would you change about the world, and how would you actually go about doing it?  Tell me what you think in the comments!

Reckless Tip of the Day: Change the world!
