Why did 99 of all species that have lived on earth now extinct?

An asteroid was hurtling towards Earth. It was a mile in width. When it hit, it was a massive mushroom explosion, causing a rippling shock wave to shake the whole Earth. It was composed of blazing hot gas and fireballs, scorching and catching anything in its path. Then a series of massive earthquakes followed, well above anything on the Richter scale. Tsunamis struck, great hulking mountains of water over 100 metres high! The big lumbering dinosaurs could not hide like the smaller amphibians, reptiles and mammals, and thus many perished amid the chaos. Finally, all the dust from the impact rose to the air and blotted out the sun. For mammals, this was ok, because they ate insects, but plants died, so their dinosaur herbivores died out, and so consequently the carnivorous dinosaurs were felled. These mighty beasts, whom had walked the Earth for so long. Killed in one single stroke from a celestial body, to make way for seemingly insignificant, tiny creatures that carved the path of life as we know it. Without them, we would not be here today.
Scientists believe the place of impact of the asteroid was a place off the Gulf of Mexico, dormant and unwaking in the seabed, until now.

∙ 13y agoSome Species are not here today because when the ice melted in the Ice Age the species were used to cold weather and it was getting warmer and some Species could not adapt as others could. Another reason is because, some species are over hunted.
