Current campaigns

  • Welcome to the Anthropocene
    The human impact on the Earth is so deep and damaging that scientists are calling for our era to be called the Anthropocene – ‘the age of humans’. Currently, too few people know about the danger the natural world is in. We’re calling on organisations which educate the public about the natural world to face the facts and inform people about the facts.
  • US cuts to global family planning aid
    We oppose the decision by the Trump administration to ban all US overseas aid to organisations which provide abortion or information about it. This decision will hit communities and countries where family planning saves lives and helps lift people out of poverty.
  • Sustainable Population Policy
    We are calling on the UK government to adopt an integrated and effective Sustainable Population Policy to address the significant challenges raised by the UK’s ongoing population growth, and the opportunities arising from demographic change.
  • Public health cuts
    We are supporting the campaign against the UK government’s decision to cut hundreds of millions of pounds from the grant that supports family planning and contraception services.
  • Increased overseas aid for family planning
    We believe that access to family planning services is fundamental to slowing and reversing unsustainable population growth.


We welcome your involvement in our activities. From writing articles for our magazine or journal to helping with outreach at events, there is a valuable role you can play. Whatever time and skills you have to offer, do get in touch. Those interested should first take out membership. We make awards to volunteers who make a particularly significant contribution. You can also join our groups (see below) who contribute to our research, educational and advocacy activities on population and sustainability issues.
