The Voluntary Human Extinction Movement. It's an organisation that believes the best future will be when people decide not to breed, so the earth is without humanity at all. It's logo is disturbingly Orwellian.
" Each time another one of us decides to not add another one of us to the burgeoning billions already squatting on this ravaged planet, another ray of hope shines through the gloom. When every human chooses to stop breeding, Earth's biosphere will be allowed to return to its former glory, and all remaining creatures will be free to live, die, evolve (if they believe in evolution), and will perhaps pass away, as so many of Nature's "experiments" have done throughout the eons. "
"The Movement is voluntary. We are promoting reproductive freedom, not "population control".
The Movement is life-affirming and will benefit all life. We are not advocating suicide, nor an increase in human deaths.
The Movement is pro-child. Every existing child deserves a good life.
The Movement is pro-parent. Existing children are in need of good parents.
The Movement is opposed to bad stuff."
Go on, ask your local Green candidate if it wouldn't be better if nobody ever had children. Ask if the earth would be a better place if there were no people around to appreciate it. Ask why your local Green candidate has chosen to breed, if he or she has done so.
