Population numbers affect everyone’s well-being, other species and humanity’s future.
We promote smaller families at home and abroad.
We publish research reports on the links between population numbers and resource security.
We develop materials on population and sustainability for teachers and others.
We lobby governments and international institutions by attending events and responding to consultations. We staff stalls, speak at fringe meetings and provide briefings.
We ask civil society to recognize that population size matters to the causes they promote.
We form local groups to raise awareness of population and sustainability, and support them with advice and materials.
