General Information:

Our atmosphere is under increasing pressure from greenhouse gases which threaten to change the climate and put holes in the ozone layer. When the atmosphere is healthy it is an efficient system able to adapt to changes. Without this ability life on Earth would be non-existent. The greenhouse gases have massively traumatized the earth’s atmosphere. Chloro-fluorocarbons (CFC) from our refrigerators and fire extinguishers destroy and damage the ozone layer. The earth is acidified by sulfur and nitrogen oxides from our cars and factories. The life expectancy of our earth as we know it, today, can no longer sustain good quality air as...
