Green Walls - All the rage

Green Walls are popping up everywhere you turn now adays. Take this one, it is located at the Siam Paragon Shopping Center in Bangkok. As everyone knows, plants help to clean the air, so having plants everywhere and any where, only makes sense. NASA has done a study on indoor plants and you can see the results here http://www.zone10.com/nasa-study-house-plants-clean-air.html

Many offices are even incorporating "Green Walls" into their surroundings, so that the air is nice and clean. Plants also lend themselves to a tranquil environment, which helps to reduce stress - which is another reason to have a green wall.
