I was born in a industrial small city which producing zinc and boats decades ago. While after few years later, lank of energy and increasing of productivity leaded many factories abandon and became a kind of city wasteland. So when I was an undergraduates student, I would like pay more attention to industrial reconstruction.
During a 7-days walking through NYC, I founded there are lots of great reconstruction landscape projects. They created landscape from old industrial site, provided different kinds of green place for citizens hanging out.
For example, High Line, Before it was abandoned railway but after reconstruction now is a great city garden.
