Human activity across the globe is rapidly pushing nature to its limit, causing loss of biodiversity and threatening critical systems that support communities. From fewer fish in our seas due to unsustainable fishing methods to half of the UK’s butterflies at the brink of extinction due to climate change and habitat loss – it is vital that we come together and act now.


We believe that nature is best protected when people are invested in its success. We bring people closer to nature, inspiring them to cherish and care about wildlife working with individuals, communities, organisations and governments to grow understanding and support for the actions needed.

    To make change happen, we bring our science and conservation work to life in meaningful and accessible ways. Through community outreach projects such as Soapbox Science and #OneLess we raise awareness of the issues facing the planet and our conservation and science work. We encourage people to take action, demonstrating how small changes like swapping single-use plastic for reusable bottles can make a difference.

    Through our respected Institute of Zoology, we offer research training through PhD studentships and host Undergraduate and Masters level research projects as part of our own MSc courses. We know the value of inspiring the next generation of conservationists. One way we do this is through our education sessions running in the heart of each of our conservation zoos.  


    As a species, we need to rediscover our wonder for wildlife. Whether it’s taking the time to explore your local environment or visiting one of our zoos to learn about the magnificent wildlife sharing our planet, your connection with nature can start anywhere.  

    With your help we can succeed

    We can't continue this fight alone, we need you there with us. Consider supporting ZSL so we can protect species at risk and give them a chance to thrive in their natural habitats.


    Making a real difference in the world isn’t just for scientists and senior politicians. Change can come from the humblest of places, such as volunteering for nature or participating in Citizen Science projects. 

    Volunteering could mean lending your time to assist on field research projects or working at London or Whipsnade Zoos supporting staff, helping visitors enjoy their day and providing excellent customer service.

    Citizen Science could be as straightforward as submitting sightings of marine animals in the Thames to help our scientists better understand where they are and what they are doing. 

    Or it could be contributing your time to listen to, and classify, the sounds wild sea birds make at sea. With people-power behind them, citizen science projects can be a cost-effective and high-impact way of gathering broad and detailed information to help protect nature. Working together on projects like this brings us all a little bit closer to each other, and to nature.
