The green belt is under attack by greedy property developers and grasping politicians. This land is protected from development to restrict urban sprawl and preserve green space for people (and for nature).
Without really noticing we've been heading towards the end of the traditional outdoors childhood. Something that many millions of adults took for granted is becoming the exception rather than the norm for today's children, where-ever they live. Roaming ranges are down, physical activity is down and the ability of children to identify common wildlife is being lost.
A year ago today I stood up in front of a room full of conservationists and told them they had failed. They exist to get people outdoors and connected to nature. But, increasingly, people are not interested. They vote with their feet, and stay indoors. More worryingly, so do their children.
