Persuasive Essay: How Dinosaurs Went Extinct?

How dinosaurs went extinct?

Seeing as how people always have their eye on the future it’s hard to know our past, for an example with dinosaurs. What exactly happened to them is a mystery; we know that they are extinct but how exactly. There are many types of theories out there like the Asteroid Impact theory, the possibility of the climate changing, and the thought out volcano eruption idea but which of these is accurate. There is more proof to support the impact theory overall and is highly considered to be more accurate among most scientists. There is an actual location of where the asteroid hit and data in the layers of the crater to support the idea that most life and organisms were wiped out after impact. On the other hand there is still

The idea that the climate had changed and ended dinosaurs as we know it is a bit hard to grasp. All throughout time species and organisms evolve; they adapt to their surroundings. Who’s to say dinosaurs didn’t? Some scientist say “Dinosaurs may have been partly to blame for the climate change. Their diets meant they emitted vast clouds of Methane, a powerful globe warming gas” (Leake) and that a normal dinosaur of that era could easily produce a thousand liters of methane a day. The claim dinosaurs unknowingly changed their own climate with their waste is a bit farfetched. This has been an ongoing event though, even today with global warming our polar ice caps melt changing our climate and ecosystem and we are still alive and kicking. Another finding in some mid cretaceous period fossils found there was a five degree Celsius drop in temperature but the evidence was controversial to say the least. “New findings show some dinosaurs thrived in cold climates. Dramatic evidence comes from Alaska 's North Slope, where William A. Clemens and L. Gayle Nelms of the University of California, Berkeley, have found signs, which they reported in the June issue of Geology (vol. 21, p. 503-506), that several dinosaur species spent the winters in cold, dark climates.” (Morell) These are very believable facts but there’s no indication that this was due to major climate change.
