Vertical gardening isn't new, but an example from India shows how this inventive technique is (true) changing lives.
The Mehra family from Amritsar were locally hot news last June when they showed off the vertical garden they had created at their home. The family used over 175, 000 plastic bottles to create garden, fixing the bottles to the outside walls of their home and filling them with (variety) of plants. The plants are irrigated by (use) a simple drip system (滴灌系统) and amazingly, this (lower) the temperature of their home by nearly a cool five degrees Celsius so far.
The idea caught on quickly. Many local schools now have green vertical gardens on their walls, so does Punjab Agriculture University, and even Ludhiana railway station, the first station in India (adopt) this initiative. The railway notes that the plants not only cool the station, but also help absorb the noise, and seem to have a calming and anti-littering effect travelers. Moreover, every vertical garden created this way is recycling plastic which would otherwise be a pollutant, actively reducing local (pollute).
