The rapid growth of our human population is pushing other species off the planet in what most scientists are calling the sixth mass extinction crisis. This population explosion continues to drive all the major environmental problems that plague our planet — including climate change, habitat loss, ocean acidification and resource depletion. The Center for Biological Diversity has been working to address the connection between rampant human population growth and the extinction crisis since 2009. Our innovative outreach and public-pressure campaigns — like our award-winning Endangered Species Condoms project — focus on common-sense solutions, including the empowerment of women and girls, the education of all people, universal access to birth control, sustainable consumer choices, and a societal commitment to giving all species a chance to live and thrive. In 2013 we expanded our population program to encompass overconsumption and sustainability, too — since these issues are intricately tied to the impact of human population on endangered species and the health of our planet. The program uses a combination of creative media, advocacy, outreach, and the expansion of our nationwide network of population and sustainability activists to keep these critical issues in the spotlight.
