Throughout history, millions of years ago, there have been five major extinctions that wiped out large percentages of Earth’s species. According to paleontologist Rolf Schmidt, more than 75% of the species had vanished during that time. Although most extinctions were caused by rapid climate change, we do not always know the precise reason. Presently, we are undergoing Earth’s sixth major extinction, which involves two main phases. However, rewind back 444 million years ago as I tell you a little bit about the first major extinction on Earth. Between the end of the Ordovician Period and the beginning of the Silurian Period, the oldest of the five extinctions took place. The Sam Noble Museum explained that the cause of this extinction was solely caused by climate change. Due to a southern hemisphere ice age, the climates cooled and took out many species. On the other hand, as the climates began to get warmer after the ice age, even more species were lost. In this, a total of 86% of species were…show more content…
In this extinction, it is known that there are two different phases. Phase 1 includes humans diffusing into diverse parts of the world. Phase 2 was focused on agriculture. Nevertheless, this extinction was caused by landscape transformations, animal harvesting, and pollution. When will this final extinction end? Well, comparing 10,000 years ago to now is equivalent to comparing 1-10 million people versus the six billion that reside on Earth today. According to Niles Eldredge, he guestimates that there will be 8 billion people on Earth by 2020, which is only two years away. The human population is who to blame for land clearing, large amounts of fossil energy use and a tremendous decrease in fish species. While conservation laws are put into place, life on Earth is not always guaranteed. For now, we can only hope that life on Earth can make a remarkable comeback just as it has in prior
