Having said that, life in general is this way. There are events outside of our control, both at the macro and micro level and we can only do our best with what is in our control.

"In comparison, the recent human-caused thinning of the ozone layer, creating "holes" over the polar regions, have only been depletions of about 3 to 4 percent, he explained."
There is no clear, compelling, imperical evidence that "humans" are causing this. There are volcanoes that have and will erupt that put out far more damaging emmissions, by orders of magnitude, than all of those produced by man since the industrial revolution...and somehow we still survive.
Species live one billion hours. How are we doing so far?
