Singapore's Green Plant Revolution

"In Singapore's next "green road map," its 10-year development plan, the country aims to go from being "a garden city" to "a city in a garden." "The difference might sound very small," says Poon Hong Yuen, the chief executive of the country's National Parks Board, "but it's a bit like saying my house has a garden and my house is in the middle of a garden. What it means is having pervasive greenery, as well as biodiversity, including wildlife, all around you."

More and more cities are waking up to the need to be more than sweatshops on a citywide scale. Singapore rose to international prominence by constructing a country that was orderly and efficient. But being globally competitive today is about more than productivity. It is about sustainability, too."

It's a strategy the city-state has employed since the 1960s.
