“The length of National Highways in the country is one lakh kilometer [about 62,137 miles]. I have asked officials to come out with a plan to plant 200 crore [2 billion] trees along these stretches which in turn would create jobs for the unemployed on the one hand and protect the environment on the other,” said Shipping and Rural Development Minister Nitin Jairam Gadkari.
Not only would this help provide jobs to a segment of the population that needs them and make the country more beautiful, but trees are also great at improving air quality . India tends to have big problems with that, as does much of Asia and the Middle-East:
A recent study shows that tree leaves can capture a substantial amount of particulate pollution. The research was conducted in the UK; The scientists started by measuring how much air pollution go into a certain number of houses in Lancaster using dust monitoring devices and by swiping surfaces and then analyzing what was collected with magnetic remanence, a technique that provides information on concentrations of iron-bearing particles.
