NOW TO CONCLUDE, ANSWER THE QUESTION. 1. ARE WE ON THE BRINK OF A MASS EXTINCTION? WHAT WOULD BE THE CONSEQUENCES FOR SOCIETY OF LOSING HALF OF ALL SPECIES BY 2100? ARE THERE ACTIONS THAT WE CAN TAKE AS INDIVIDUALS AND AS SOCIETY TO HELP PROTECT LIFE ON EARTH
We have looked at what the fossil record can tell us about the amazing History of Life on Earth. We've examined the evidence for an early origin for life in the sea, 3800 million years, and investigated how life invaded life about 500 million years. We've also discussed the subsequent boom in life that massively increased biodiversity but also noted how the History of Life is frequently punctuated by mass extinctions. Today we stand on the threshold of a new mass extinction event. The biodiversity that we take for granted and that sustains humans is threatened to a degree only rarely seen in 4500 million years of Earth History.
