Next years Olympic games in Beijing China will feature greenery incorporated, environmentally-sustainable footpaths for the millions that will walk the Olympic Forest Park - the multimillion-dollar, 680-hectare space built for the Olympic Games. Score one for the environment but if you're planning on going to the games, make sure to wear sturdy footwear as these footpaths look little a twisted ankle waiting to happen.
