Singapore has built a huge, eco-friendly Supertree Grove

Singapore has built a huge, eco-friendly "Supertree Grove," made up of unique tree-shaped structures, up to 16 stories high, that collect rain and solar energy, absorb heat and provide shade to visitors and residents. The city is so green-focused that it's committed to zero waste in landfills by the middle of this century, and it was also the first to introduce the congestion charge. Traffic can get so bad that the city introduced a network of real-time cameras, sensors and GPS to track traffic and predict where jams will be, charging drivers more in that area. But don't think that Singapore has forgotten about pedestrians -- the disabled and elderly are given smart RFID (radio-frequency identification) cards which extend crossing times at traffic lights.
