Ironically, a plan for fake trees only exists on paper right now. Dr Klaus Lackner, from Columbia University, has proposed a “fake tree” that can clean the air of CO2. The tree can the air of 90,000 tonnes of CO2 a year.
Right now it is cost-prohibitve to build the fake trees because the filtering material is very expensive to recycle. Dr. Lackner sees making artificial ways to clean the air of car emissions ,and other CO2 sources, has a very important step in saving the planet.
