It
is a purified world in Kerala, the land of trees. A big, spreading
tree purifies as much air as a room air-conditioner. And the former
is never switched off. The prolific, bustling, vegetation acts like
a massive, biological, air-filtration plant working round the clock,
round the year. Hence spending days in Kerala countryside is as if
spending in an air- purified environs; some times better than it. So
is the rejuvenating effect of the lush greenery of the state. |
