because usually we could run out of an important predators and their would be more of the same creature that we need

That no species is stable, and that all species become extinct in time. That includes us.
It is "bad" that any species is endangered. Endangered species can become extinct species, reducing the worlds biodiversity and potentially robbing us of knowledge that might be beneficial in the future. it will wreck the food chain the animal the snow leopard eats will get over populated the one that the overpopulated animal will get underpopultated and it goes on and one day will affet us
Many people around the globe will be sad <(;_;)>
No, all four species are alive and well. In fact, it was recently found the two of the five species were actually the same species and were combined to give us the four current species.
The extinction of a species would mean the death of a species. Every species has its own niche (or role) in its ecosystem. For example:Carnivores --eat--> Herbivores --eat--> Plants --get nutrition from--> Decomposers --eat dead things. It's an (albeit very small and simple) circle of life.Now if the herbivores were to go extinct, so would the carnivores. If the carnivores were extinct, then the herbivores would eat all the plants until the plants were extinct, and then the herbivores would die of starvation. There's a balance to things that would be crumbled and ultimately, the ecosystem would be very negatively affected if not destroyed.In addition, through studying other species, science can extend its knowledge. Some species have natural adaptations to problems that plague us humans. If science can figure out how those species deal with the problem, that solution could be modified to fit humans, too. If that species goes extinct, that possibility is lost.
they never did die out, but they evolved into a more clever species with larger brain spans and carried on evolving into us (homo-sapiens)
It actually doesn't matter the length of time. When the last animal of that specific species is dead, the the animal is proven to be extinct. Sometimes animals are thought to be extinct, then are re discovered, as the case of the ivory billed woodpecker in the U.S. It usually takes many years after the last sightings of an animal before it is declared extinct. In some cases the last known animal of a species is in a zoo so when that animal dies the species will be declared extinct. This was the case with the passenger pigeon which was hunted to extinction in the early 20th century. The last passenger pigeon died in the Cincinnati Zoo in 1914.
Extinct animals are species that once existed but can no longer be found anywhere in the world. Dinosaurs are extinct as is the bird known as the Dodo. Living animals are still with us.Extinct animals are species that once existed but can no longer be found anywhere in the world. Dinosaurs are extinct as is the bird known as the Dodo.

Animal endangerment affects everyone to some degree. When an animal goes extinct, future generations can only read about these creatures, and those of us that created the situation for such extinctions must bear the blame. Animals in trouble must be protected at all costs, for as a scholar once said, "When an animal goes extinct, Heaven and earth must pass away before such a one is seen again".
There are far too many extinct animals to list. In fact, the vast majority of animal species that have ever existed are extinct now. Some of the most famous include the dinosaurs, mammoths, and saber toothed cats, but that is only a miniscule fraction of the total amount of extinct animal species.
