Who needs paint (or wallpaper for that matter!)? These walls are not only G-O-R-G-E-O-U-S but have environmental benefits as well. Read this blurb from the Sustainability Institute and then get out your green thumbs:
The benefits range significantly. The most obvious is an improvement in air quality. We all had to learn the process of photosynthesis - the absorption of carbon dioxide and the release of O2 as a bi-product acts as a natural air filter. For those outdoor walls, urban bio-diversity is enriched and created is a provision for outdoor wildlife habitats. It creates an attractive urban space while also protecting the fabric of a building from UV rays and acidic rain. If the green wall is on the southern-facing wall of the building, it helps to regulate temperature within the building, lessening the demand on the HVAC system. These walls also drone out traffic and other urban noise.
It's easier than you think Kermit (and prettier too!)
