How many species become extinct per year? Best Answer: 16 species become extinct each day. That is 21,894 a year. Go onto this site, it will give you the numbers for a day or a week, or a month for all sorts of things from population growth to numbers of computers produced. Oh well, about ten years ago, it was only around 1 or 2. But NOW, because of those global warmingists (oop), its between 3 and 23845923874 species per week.

5 Animals That Have Gone Extinct In The Past 50 Years 5 Animals That Have Gone Extinct In The Past 50 Years. May 31st, 2015 by James Ayre. The rise of industrial civilization over the last few hundred years has been accompanied by the extinction of a truly vast number of different animals (as well as plant, fungi, etc) species.eople being how they are, I’m going to focus here on some of the more charismatic (to the eyes of a human) and immediately recognizable of the animal species that have gone in extinct in recent times. With that said, here are 5 animals that have gone extinct in the past 50 years:

Mass Extinctions An asteroid impact is another possible cause of the extinction, though a telltale crater has yet to be found. Largest Ever Die-Off. The Permian-Triassic extinction event about 250 million years ago was the deadliest: More than 90 percent of all species perished.s new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 50 to more than 90 percent of all species on Earth have disappeared in a geological blink of the eye.

THE EXTINCTION CRISIS No group of animals has a higher rate of endangerment than amphibians. Scientists estimate that a third or more of all the roughly 6,300 known species of amphibians are at risk of extinction [ 6 ]. The current amphibian extinction rate may range from 25,039 to 45,474 times the background extinction rate [ 7 ].obody really knows how many species are in danger of becoming extinct. Noted conservation scientist David Wilcove estimates that there are 14,000 to 35,000 endangered species in the United States, which is 7 to 18 percent of U.S. flora and fauna.

Could sharks be heading for extinction? According to the International Union for the Conservation of Nature Shark Specialist Group, 28 percent of shark species are at risk of extinction. An estimated 100 million sharks are killed annually, Worm and other researchers estimate, 20 million or more per every fatal shark attack. And that wholesale slaughter could already be sending dire consequences cascading down the food chain, much to the bane of scallop and lobster lovers.

Extinction event 1 Earth's largest extinction killed 57% of all families, 83% of all genera and 90% to 96% of all species (53% of marine families, 84% of marine genera, about 96% of all marine species and an estimated 70% of land species, including insects).2  The highly successful marine arthropod, the trilobite became extinct. This extinction event lasted perhaps as long as 20 million years, and there is evidence for a series of extinction pulses within this period. 2  Ordovician–Silurian extinction events (End Ordovician or O-S): 450–440 Ma at the Ordovician-Silurian transition.

Effects of Human Overpopulation Compared to the natural background rate of one extinction per million species per year, we are now losing 30,000 species per year, or three species per hour, which is faster than new species can evolve. The chart below further exemplifies the correlation between human population and species extinction.
