Maybe not for food, but for happiness? I would say so.Yes, actually, it is. That's why we're not starving in the capitalist countries. Wierd, ain't it?
Eruptions like that don't happen everyday. I don't know if this is true or not, but it would seem likely that in between the time that eruptions like that occur, the ozone could repait itself. When humans cause this it can't repair because it doesn't ever stop. Again, I don't know if that is true, it just seems logical.Second, the eruptions of Mt. Pinatubo in the Philippines and Mt. Hudson in Chile caused a 15-20% loss of ozone in the high stratosphere and 50% over the Antarctic. And here's one with pictures. One eruption, 20% loss.
