Ofcourse this is going to put pressure on the environmental balance tilting towards the negitive side, but its everybodys responsibility to take care of the environment, not just the have nots. Its not that haves can shit/screw up the environs and have nots clean it. Its everybodys responsibility to think of environment.Its again the same call, are we trying to consider the environmental effects or not, irrespective of what we have, a Lexus or Nano. Having said that, we should just appreciate Nano for coming up with such a less price and making lesser mortal's day by giving the pleasure of having a car.
