One example of this is the way the world community dealt with the hole in the ozone layer caused by fluorocarbons. This alarming problem, documented by solid evidence, had to be solved for life on earth to continue. And it was. In 1978, governments and businesses worked together to eliminate fluorocarbons in aerosol cans and other products. Today the hole in the ozone layer is disappearing. Scientists believe it will be back to its ideal level by midcentury. This happened because governments and corporations all over the world worked together to stop an impending catastrophe.
