Diana,

What you say has much merit.

It's amazing how quickly this Mt. St. Helens blast zone out here has
recovered, both with plants and animals. The pyroclastic flows were
clocked at nearly 300 mph, and about 800 degrees Celsuis. That is bright
cherry red heat... It certainly totally sterlized the earth for miles, but
life returned.
