He sprayed the trees with rainwater collected by the reservoir so that they could grow faster and absorb more contaminants.
He urged the new government of India to ask for rainwater collection and white paint on roofs and buses.

Wendy KochNASA published several studies in the 1980 s showing that indoor plants can purify air in a sealed test room similar to the space station.
Later, it tested the value of plants to clean air and recycle waste in a tightly sealed building called BioHome.
Subsequent studies have also shown that plants can help clean indoor air.
In 2009, a research team at Penn State University found through greenhouse experiments that plants could reduce indoor ozone emissions from photocopiers and laser printers.
