If the ozone layer
was brought down to the Earth's surface, air pressure and temperature
conditions would compress the ozone into a layer 2 to 5 mm thick!
If all ozone-depleting
chemicals were successfully phased out, the ozone layer would eventually
heal itself.
We don't need a tan
to be healthy. Protect your skin from the sun: spend less time in the
sun, especially when your shadow is shorter than you! Cover up! Wear a
hat, long-sleeved shirt and long pants. Use a sunscreen of SPF 15 or greater.
Stay out of the sun between 11.00 am to 3.00 pm.
