Habit- That easy way out......taking a motored vehicle to even the nearest of places.....and public transport just won't do...it has to be my own car...my own scooter......or my reserved auto!
Solution- something Doordarshan propagated many years ago.....start paddling.....or walking...as the case may be.....or get on that train or bus!!
Extreme- my first solar car!!
Did ya hear about- walkways in malls that generate energy from the foot pressure of people walking on it??
