He also has a plan to darken the sun. The Soviets had a similar plan during the Cold War. Using the same chemical calcium carbonate. https://www.washingtonexaminer.com/opinion/bill-gates-is-trying-to-dim-the-sun
A volcano in 536 a.d. darkened the sun causing lots of crops to die. There was world wide famine. https://en.wikipedia.org/wiki/536

Bill Gates is a sociopath. He has no human compassion so he could potentially do anything.
