Founded by John Feeney, PhD, an ecological writer and activist based in Boulder, Colorado, United States, GPSO is designed to boost public discussion of human population as a key factor in the struggle for sustainable living on earth.
Scientists, representatives of environmental NGO’s, science writers and activists, along with ordinary concerned citizens are targeted.
Dr. Feeney conceived of the GPSO idea in 2008 and organized and managed the first Global Population Speak Out in February 2009.
Among them was John Guillebaud, Emeritus Professor of Family Planning & Reproductive Health, University College London, and former Co-chair of OPT.
There were 24 women and 26 men, who represented 16 nations, including: Argentina, Australia, Bangladesh, Chile, Ethiopia, Germany, India, Italy, Kenya, Portugal, Singapore, Thailand, Uganda, UK, and the USA.
