A new report to government has arrived that states there is an economic aspect to green spaces. Moreover, people who have access to green space have better health prospects. Quite how anyone works out how much going for a walk is worth I do not know.
Professor Bob Watson, chief scientific adviser to the Department for Environment, Food and Rural Affairs (Defra) is quoted as saying –
"Urban green space, for example, is unbelievably important - if affects the value of houses, it affects our mental wellbeing.
"This report is saying 'this has got incredible value, so before you start converting green space into building, think through what the economic value is of maintaining that green space' - or the blue space, the ponds and the rivers."
