Give a reason for the extinction of dinosaurs What species is now in danger of extinction

Mass extinctions: number sixPalaeontologists recognize five major extinction events from the fossil record, with the most recent, the Cretaceous mass extinction, ending some 65 million years ago.Given the many species known to have disappeared in the past few thousand years, some biologists suggest that a sixth such event is now under way.Barnosky et al. set out to review the evidence for that claim, and conclude that the recent loss of species is dramatic and serious, but not yet in the mass extinction category - usually defined as a loss of at least 75% of Earth's species in a geologically short time frame.But that said, there are clear indications that the loss of species now classed as 'critically endangered' would soon propel the world into its sixth mass extinction.
Yes, however they were pushed to the brink of extinction by commercial whalers. They are now under the in dangered species list.
Human intervention saved this species. Many were raised in captivity, and now around 400 are back in their former haunts.
Two examples of species that have been brought back from the brink of extinction are the American bison, which was once hunted to near extinction but has since recovered through conservation efforts, and the California condor, which was down to only 27 individuals but now has a population over 400 thanks to captive breeding programs.
Pandas have been listed as endangered because people have been hunting them and they are close to extinction.
Extinction has happened to the dinosaur family.
No reason to believe they will. They are a cultivated species and in no danger of extinction.
Global warming changes natural habitats making them unliveable for many species ==== Global warming was the first effect identified that was shown to lead to species extinction events. For instance, a mountain frog would migrate from lower to higher elevations annually to survive. The species is now extinct because of global climate instability. The frog reached the top of the mountain and it was still too warm and their species died, all of them; extinct. There is a difference between Mass Extinction and Global Extinction. Mass Extinction is where a large percentage of a species dies. -- This is like a plague that wipes out 90% of a species Global Extinction is where the entire population of a species becomes extinct. -- This is like the mountain frog, it is completely extinct -- Melting of the Methane Permafrost could release enough methane to kill all humans Total Extinction is where all species globally become extinct; including ourselves. -- A large asteroid, black hole on a trajectory with our solar system, a near region super-nova, super-volcano eruption, abnormally large Solar Mass Ejection, ...
