fact: 43 years from now, by 2050, it is predicted that global temperatures will have increased to 2 degrees above pre-industrial levels, which will cause irreversible damage to the planet. A 4 degree rise in global temperatures could cause all the world's glaciers to melt.
act: 43 years isn't that long - just ask someone who's just reached their 40th birthday. Take your car to get regular tune ups. An improperly tuned car can emit as much pollution as 20 cars that are properly maintained.
