Try to kill everyone in the world indirectly. How will you do it?

You're an average citizen living in Purple Lake, in the State of Plus. You have a salary of about $80,000 a year. Since you hate humanity, you have decided to try to kill everyone in the world because you're literally crazy, and don't have anything better to do.

Note: After you attempt this, you will get kicked from your job and cannot earn any more money to fund your project.
