One major event of earth's history was during the Holocene era. This is the time period where humans evolved and populated the earth. The Holocene era goes from 11700 years ago to now. Humans have changed the earth a lot, with pollution, global warming, destroying habitats, and making species extinct. Another major event of earth's history was the extinction of dinosaurs, which happened near the end of the Cretaceous era. This changed the planet because without the extinction of dinosaurs, humans might not exist today. Before, dinosaurs were the dominant race, but now humans are. Another major event of earth's history is the Cambrian period. It is when animal phyla in increased in diversity suddenly. This is also the time when different groups of animals started to appear on the fossil record.
What was surprising about the scale of earth's history is the fact that humans were around for such a short time. Dinosaurs were around longer than humans, and they went extinct. Humans have a chance of being extinct, along with all the other species that live on earth.
In the short time humans have been on earth, we've done a lot. We have made a hole in the ozone layer, which effects the earths atmosphere, which will effect life on earth later. We have also made things that are hard to dispose, like glass and plastic. But with earth's history being on such a large scale, they will decompose.
How long will humans live on the planet before it runs out of resources, or we become extinct?
