An extinction event (also known as: mass extinction; extinction-level event, ELE, or biotic crisis) is a sharp decrease in the diversity and abundance of macroscopic life. They occur when the rate of extinction increases with respect to the rate of speciation. Because the majority of diversity and biomass on earth is microbial, and thus difficult to measure, mass extinctions have little effect on the total diversity and abundance of life, but rather affect the easily observed component of the biosphere.[1]
