Had forgot that one while writing my last post. But I've seen the same episode you referred too.Thanks for that post!
I just watched a program on the caldera of Yellowstone national park.. program on Smithssonian..really amazing place .They were saying when that one blows ,it could ,with focus on the word could , create a cloud that blocks the sun for years possibly and what I took away from that was basically game over man , maybe a few could survive .. I'm not sure how without the sun for five years..??
Also, related to this subject, there's other angles that some folks don't fully explore. For example, a lot of trees are growing more wood now than they have in the past few centuries.
There is a claim that there are 46% less trees now during man's involvement. And a recent study indicates there are over 3 Trillion trees on Earth, more than 6 times previously estimated. Personally, I think the 3.04 trillion estimate is probably low and there's even more than imagined.
But I'm curious how much wood, canopy and root exists now compared to past millenniums ... ?????
If a lot of trees are putting on growth and new wood at increased rates, is is possible that 3 trillion trees can do the job of 6 trillion trees?
