For every 1,000 Km the average car uses the same amount of oxygen a person needs to live for 35 years!!!
Today, scientists are concerned about the oxygen levels in major cities across the world. In some places the levels were shockingly low.
Even though our atmosphere is mindbogglingly huge, it is incredibly sensitive and fragile. Other industries like steel, gas, coal and cement remove vast quantities of oxygen from the air we breathe.
We are literally going to run out of oxygen in a few thousand years. THE SKY IS NOT FREE!
