Why a TWO child average will not solve overpopulation



With a two child average per woman (or per man), total population would go up by about two billion more before it even levels off! We must begin dramatically reducing births now – in order to achieve sustainable population and a viable planet for all people.

One child families can humanely solve overpopulation!



By averaging one child, total world population would be about 1/3 of our current population in 100 years. Exponential population decline can help humanity return to a truly sustainable number of people on the planet.

One child families can save the world.

Overpopulation is destroying the planet and our future



Our world is in a human well-being crisis . Every year 75 million more acres of farmland are destroyed and lost to farming, net loss (UN). Over half the world's 7+ billion people are in countries where fresh water tables are falling.

. Every year 75 million more acres of farmland are destroyed and lost to farming, net loss (UN). Over half the world's 7+ billion people are in countries where fresh water tables are falling. We are destroying 25 more acres of forest every minute, net loss (FAO). One million animal and plant species are now threatened with extinction, more than ever before in human history (UN).

Overconsumption of many "renewable" resources is rendering them nonrenewable. Alarmingly, we are consuming many non-renewable resources – fossil fuels, metals and minerals – at ever-increasing rates, as well.

We are struggling to live healthy lives on a dying planet. And many people are deluding themselves into believing that we can grow our way out of these problems.

And many people are deluding themselves into believing that we can grow our way out of these problems. According to research by the Global Footprint Network, we humans are currently consuming renewable resources over 75% faster than the truly sustainable rate. We are in consumption overshoot.

To stop global overconsumption, depletion of resources and unprecedented loss of species – and significantly reduce dire human poverty – total world population needs to be between 1 and 3 billion people. That is the population range to be truly sustainable, long term, on the planet.

Therefore, the most important single action each of us can do to help create a truly sustainable planet and population is to choose to have one child and encourage others to have one child. (See the five minute film, "One Planet, One Child".)

We can solve overpopulation humanely.

Signers - Sustainable Population Pledge



Sarah Richter- U.S. - "I am a 22-year-old young woman and recent college graduate. I am childfree by choice and hopefully will be sterilized soon! What I read and see in the media confirms my decision on a daily basis. Having children in spite of climate change, growing social disparity, and overpopulation is dangerous. I want to use my freedom to enact change in hopes of a brighter future. Thank you for your podcast! It inspires me to continue this lifestyle and activism."

Maralei Bunn - U.S.

Rebecca Bishop - United Kingdom

Joe Ho - Hong Kong

Mohamed Alhusni - Qatar

Steve Laking - United Kingdom

Celine Nouvel - U.S.

Abhisek Sharma- India - "To remain in harmony with nature and finite resources encouraging everyone is the only solution. Lives will be much better. I support fully your work. Thank you."

Nandita Bajaj- Canada - "Not having children is one of the most important decisions that my husband and I made for our planet, our home, over 10 years ago. While our decision revolved around addressing the overpopulation crisis, we have thrived tremendously in a childfree relationship. We are a stronger and more fulfilled couple as a result, with time and resources to give back to our human and non-human animal communities that need it the most. We couldn’t be happier."

Amber Sealy - United Kingdom

Aubrie Barkenhagen - U.S.

Ali Bagheri Tirtashi - U.S.

Piers Leveroni - United Kingdom

Vince Mastrocola- Canada - "I am hopeful that the population growth rate can be altered so that we never reach 10 billion before starting to descend to the 3 billion level that would allow humanity to sustain itself without further destruction of the planet."

Crystal Kennedy - U.S. - "We need to be more compassionate and stop letting our egos tell us that our genes are so special that we have to reproduce because this is biology, and sometimes our biology does not know what's best for us. We need to be smarter than our biological drive to reproduce."

Katherine Schwarz - U.S. - "I think there should be a Non Mother's Day to recognize those of us who chose not to have children and model that lifestyle. So many women feel pressured by society, by their peers, by their mothers or mothers-in-law to have children and women who choose not to are made to feel inadequate and made to feel like they will never have a fulfilling life if they are childless."

Katherine Kooyman - U.S. - "I needed this website right now to remind myself NOT to have a second child!"

Shivaani Kulanthaippayan - Malaysia - "My sisters and I are from conservative Hindu Family who's all about marriage and bearing children. All I can say is that we are definitely going childfree and we will continue educating and create awareness as far as we can go."

Peter Fiekowsky - U.S. - "Pledging to have a small family is the most potent climate action any individual or family can make. It saves 100 times more carbon emissions than being vegan your whole life. As founder of the Foundation for Climate Restoration, I encourage everyone to take this pledge."

Janice and Stephen Blakeney - Australia - "We are committed to helping others understand the gravity of the global climate emergency and its roots in the impact of human population growth.

Brendan Anderson - Canada - "What good is having more people in the world if they can never experience the beauty of the Earth, or if they have to viciously compete in poverty for the limited resources on our planet? I just want the humans of the future to live in a world full of beauty, plenty, peace, and prosperity. None of that is possible if we keep living the way we do in the numbers we do."

Carmel Morris - Australia - "I have been told 'It's selfish not to want children' (I don't have my own, only one adopted son) but now I hear more often, 'It's selfish to want children,especially more than two'."
