Talia Randall talks to the nature-loving pioneers who are smashing down the barriers–visible and invisible–that keep so many of us locked out of green space. From a park in Glasgow, to a beach in Cornwall and a Traveller site by an A road in London. Nature can help us work out who we are. Take Ione, a British-Mexican land worker who finally understood what it meant to have a mixed identity when she saw a Mexican plant growing in English soil. As a kid, Talia broke into the nature reserve on her council estate. Some call this trespassing, others call it playing out. Which children are allowed to play in nature freely and which kids are seen as a threat? Now that Talia isn’t that kid anymore, she reflects on her own relationship to nature, has it changed as her class has?
