Perhaps they should check out this website

VHEMT (pronounced vehement) is a movement not an organization. It's a movement advanced by people who care about life on planet Earth. We're not just a bunch of
misanthropes and anti-social, Malthusian misfits, taking morbid delight whenever disaster strikes humans. Nothing could be farther from the truth. Voluntary human
extinction is the humanitarian alternative to human disasters.
We don't carry on about how the human race has shown itself to be a greedy, amoral parasite on the once-healthy face of this planet. That type of negativity offers no
solution to the inexorable horrors which human activity is causing.
Rather, The Movement presents an encouraging alternative to the callous exploitation and wholesale destruction of the Earth's ecology.
As VHEMT Volunteers know, the hopeful alternative to the extinction of millions of species of plants and animals is the voluntary extinction of one species: Homo
sapiens... us.
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 Mother Nature's "experiments" have done throughout the eons. Good health will be restored to the
Earth's ecology... to the "life form" known by many as Gaia.
It's going to take all of us going.

Sounds like a good way to chlorinate the gene pool.
Did I mention the VHEMT stands for Voluntary Human Extinction Movement.
