Join Edward Mayer, from Swift Conservation as he talks briefly on just how important urban biodiversity is for us all.

We know that the built environment has become a place to survive for many species as the countryside, treated with agricultural chemicals, has become more hostile, and that those who share our buildings - Swifts, House Martins, Starlings, Wagtails, House Sparrows and Black Redstarts as well as Bats, need places to breed and feed.

By "greening" our towns and adapting our buildings we can keep them with us as well as provide the green spaces and green "lungs" that provide us with the vital environment to support our physical and mental health.
