Maybe it’s time to put a hold on the production of new cars for a while.
According to WardsAuto.com, the number of operational vehicles worldwide passed the 1 billion mark in 2010. And with around 60-70 million new cars selling every year, it will take only 15-20 years to double that amount.
While the odds are slim of actually getting to the point where cars outnumber the almost 7 billion people on Earth, it’s alarming that humanity has the need for over a billion carbon-emitting, fuel-drinking machines to satisfy our transport needs. According to some quick Wiki research, there are about 5 billion people on Earth over the age of 15, which would give an approximate car-to-driver ratio of 1 to 5. By that logic it would seem the current supply of vehicles is about in line with the world’s need.
However, since many developed countries, especially the U.S., consist of people who hoard as many cars as they can, ratios in specific countries tell a much different story.
