X is for eXtinction

My theme for my 2015 A to Z Challenge came from my Disaster Crimes series. Disasters are a theme in each story, so it got me thinking about all the disasters that occur from natural disasters to manmade disasters.
Today’s disaster is...EXTINCTION
Sixty-five million years ago all dinosaur life on Earth became extinct. More than half of the world’s species obliterated. How? Well, that answer hasn’t exactly been answered. Most scientists lean toward an asteroid or comet hitting the Earth. This theory is supported by a layer of rock dated to the extinction event that is rich in the metal Iridium and is found all over the world. Scientists believe this Iridium was scattered by the collision of an asteroid or comet.

FACT: A 110-mile-wide crater in Mexico's Yucatán Peninsula has since been dated to 65 million years ago. Many scientists believe it is this impact that caused the dinosaur extinction.
Another theory is that volcano eruptions are responsible since Iridium can be found in magma. Some scientists even believe both theories could’ve been the cause. In either case, they all agree that dense clouds of dust and toxins blocked out the sun’s rays, darkening and chilling the Earth. When the dust settled, greenhouse gases caused the climate to skyrocket. The freezing then boiling of the world is the ultimate cause of the death of 70% of all plant and animal life on Earth.
