Rays can pass through to reach the earth’s surface. The Ozone is a layer that protects the earth from UV rays however the layer is reducing because of harmful gases.
CFS’s are the harful gases and they have destroyed the ozone layer, as can be seen in the maps in this video, since 1982 to the 21st century the ozone hole has massively increased. BUT WAIT, there is good news.
The Ozone has started to heal. Thanks to the Montreal protocol which prohibited ODS (Ozone depleting substances) the hole has begun to heal. In order to continue this wonderful recovery we as consumers need to chose the biodegradable roll on’s instead of harmful under arm sprays.
With a bit more conscientious purchasing we can keep the good news coming in.
