Towns and cities

Are we doing enough to make our towns and cities sustainable? Is green thinking making a difference? We are all aware of the importance of the environment - it's always in the news and it affects our behaviour and the decisions we make every day.

This thought-provoking series looks at the way changing ideas about the environment and sustainability have affected our landscape, conservation efforts, transportation, food and farming, and our towns and cities.
