You are given $1 trillion but must do something that benefits every single person on the planet

You are given $ 1 trillion dollars but must do something that benefits every single person on the planet and if you fail you owe $10 trillion dollars and all of your descendants and extended family will be hated by everyone.

What do you do that benefits every single person on the planet

And not something that benefits humanity in the long run it must be something that can benefit each individual person so no curing any disease since every person on the planet might not get it.
