That is what Bill Gates said:
"The world today has 6.8 billion people. That’s headed up to about nine billion. Now, if we do a really great job on new vaccines ... we could lower that by, perhaps, 10 or 15 percent."

Bill Gates is responsible for ...
... sterelizing women around the world without their informed consent.
... mutating and murdering children around the world (on trial in India).
That is why many people say: "Bill Gates is a mass murderer who has to be arrested."
