Super Tree Device Purifies Air in Polluted Cities

Super tree If you travel to Lima, Peru, try not to breathe the air: according to a 2006 study, the bustling city’s air quality surpasses the international standard of persistent toxic substances per cubic meter by more than 122 percent.However, a new device known as the “Super Tree” may help to purify the polluted city. The Super Tree’s effect is equivalent to planting 1,200 trees in the city to help purify the air and reduce fuel emissions and other toxins, providing cleaner air for up to 20,000 people per day. Each Super Tree costs about $100,000, which works out to just $6 per day for the device’s lifespan.The city has only implemented one Super Tree so far, but the mayor of the Surquillo division has already committed to purchasing at least 20 Super Trees to be placed throughout the urban area. The company that invented the Super Trees, Tierra Nuestra, hopes to install 400 Super Trees throughout Lima within the next four years, and eventually go on to sell the device internationally. For smoggy cities like Pittsburgh and Los Angeles, a few Super Trees could be just what Mother Nature ordered.Learn more about Tierra Nuestra’s invention from their homepage.How you can help: Short of bringing a Super Tree to your city, there are plenty of ways to clean up the air around you.
