Technology has got the answers to most of our problems. Inspite of our likes or dislikes, we cannot revert back to riding on horses / bullock carts in this age for transportation. Only that new technologies has to answer the problems of fuel consumption, raw material usage at the earliest. I am sure and hopeful that global warming will be reversed in the near future because of scientific technology. Technology is the answer to global warming. Kudos to Tata for bringing up a fantastic fuel efficient car. Jai Ho Tata !!
