For some children, the chance to run wild and free in a big grassy field, is a far-off dream they might never experience. Disadvantaged urban living is leaving many children around the UK with a poverty of experience, particularly when it comes to nature. One charity and its farmers are trying to change that though. Jez Fredenburgh speaks to Mary Hext at The Country Trust, which takes thousands of children a year to visit farms, and Michael Gent, a host farmer in Northamptonshire, about why sharing the countryside with the children is so rewarding.
