A number of scientists grapple with improving methods for estimating extinction rates. It’s hard to pinpoint the exact extinction rate because many endangered species have not been identified or studied yet. ![]() Recent studies estimate about eight million species on Earth, of which at least 15,000 are threatened with extinction. Helena olive tree – extinct from logging and plantations 1989 Golden toad – extinct from climate change or other impacts.1962 Hawaii chaff flower – extinct from habitat conversion to military installations.1952 Deepwater cisco fish – extinct from competition and predation by introduced fishes.1936 Thylacine (Tasmanian tiger or wolf) – extinct from hunting, habitat loss, and competition with dogs.1900 Rocky mountain locust – extinct from habitat conversion to farmland.1870 Labrador duck – extinct from human competition for mussels and other shellfish.1768 Stellar’s sea cow – extinct from hunting for fur and oil.1690 Dodo bird – extinct from predation by introduced pigs and cats.The passenger pigeon is one of many hundreds of extinctions that have been caused by human activities in the past few centuries, such as: The last passenger pigeon, named Martha, died in the Cincinnati Zoological Garden in 1914, and was donated to the Smithsonian Institution. Commercial hunters killed them in vast numbers, eventually decimating the population. Easy to trap or shoot, passenger pigeons became a popular, cheap food. Until the early 1800s, billions of passenger pigeons darkened the skies of the United States in spectacular migratory flocks. One of the most dramatic examples of a modern extinction is the passenger pigeon. It's also entirely unknown what the population of Mars was since it was destroyed billions of years ago, so only the fish accidentally killed by Scrat will be counted.Extinction is the death of all members of a species of plants, animals, or other organisms.It's entirely unknown what the population of Scratlantis was before it was sunk into the ocean by Scrat.(He is only seen being chased by the Raptors) Orson - Presumably killed by the Raptors.Two Raptors - Knocked into the air by Momma.Three Members of Buck and Zee's Team - Killed by Orson.Fish - Disintegrated after Scrat crashed into Mars.Green Siren - Disintegrated shortly after Scrat crashed into the planet.Bird - Burned alive by the heat of the sun.Ariscratle - Drowned as the Scratlantis was flooded away by Scrat.Captain Gutt - Eyes gouged out and eaten by a siren offscreen.Shark - Died when Granny jumped into the water.Ten Fish - Died when Granny jumped into the water.Rudy - Pushed off a cliff by Momma Dinosaur.Two Guanlongs - Kicked from a high height by Manny.Four Pterodactyls - Incinerated when they flew into lava in pursuit of Buck, Crash, and Eddie.Two Guanlongs - Knocked out by Diego and fell off a high height. ![]()
