•Cause of that? –Volcano, Asteroid, or Comet –Evidence points to Volcano
–Evidence for Volcano:•Sulfur in polar ice cores•Book of Kings•Charcoal Samples- not enough evidence to prove, but does not rule out

Catastrophe!Catastrophe! This event impacted the entire globe
with crop failure and sickness.
Cooler temperatures and unpredictable rainfall allow plague bacteria to grow and also increase rat population.
~This is relevant today because it shows one way in which climatic events impact disease. Sudden changes (both increases & decreases) in temperature and rainfall will impact both human health and crop production, and climatic change causes changes in both areas. This is significant to us because we are currently undergoing major climatic warming. ~

Crop Agriculture and Domestication of Animals made it possible for some to
spend less time & energy feeding themselves; thus they were able to put time & energy into advancing
