There are too many people already. Why do you think so many companies are working on life shortening and population reduction technologies?

What companies are doing so?

Governments, through the military. And... yes, they're companies.

Monsanto, ConAgra, Gates Foundation, pretty much every major food company, all pharmaceutical companies, tons of government think tanks, AMA, etc..

Your description of what these companies do is distorted. They are not actively developing technologies with the purposes that you described or even as any such consequential purpose.

Tell yourself what you need to.
