If you look at the last 50 years or so you can see where we went wrong in the UK. Instead of tall garden cities where the air is clean and people walk, cycle or use public transport to move around, we have an obese urban sprawl that often reflects the waistlines of many of the people. Where we should have built up, we have built out. More little boxes, more sterile patches of mown grass, more roads and of course more cars. Our whole economy is geared to producing more and consuming more in an ever increasing attack on the diversity of nature. Whereas we could plan and work near we live everybody needs a car to get a decent job. Just check the motorways on any given morning. This pollution and waste of people’s lives could have all been avoided if we had designed a better built environment. If we are not careful our country may still be green but a green dessert devoid of diversity.
