Our Atmosphere Needs Protecting.

So, just how far away is 'space'? The Federation Aeronautique Internationale has established this to be an altitude of 100 km or 62 miles, NASA considers people to be astronauts once they've travelled higher than 80 km (50 miles).

Oxygen in the atmosphere runs starts to run low at 12,000 feet, about 2 ¼ miles and Mount Everest, you have to be very fit to climb her, is ‘only’ 5.497 miles high and many have died there without oxygen.

The NASA image seen on the left shows just how thin the earth's atmosphere is relative to the earths's size, evident in its radius. This scene captures the silhouette of several thunderstorms with their cirrus anvil tops spreading out against the tropopause, the first dark blue line over the earth. The height of this varies according to where it in Lattitude, it can be between 6 and 8 miles high and temperatures can be as low as - 80c.

It is the thin area below this that needs our protection and the reason why pollution control is so important in maintaining God's creation for future generations.
