Just look back our grand-fathers who lived life so peacefully and healthy. The present humans are not humans, they are spoiling everything on earth believing they will live 100 yrs. Believe we are not going to live more than 30 years, see nowdays young people are getting heart attacks. Information Technology is worst industries and the root cause for global warming. We should ride cycles instead of bikes and bikes instead of cars. Cars instead of flight then we can save the globe.
