Extinct species are gone. There are no members left alive. Therefore, there is nothing one can do for them.
So the species does not become extinct.
Each species is apart of a greater relationship which sustains the current life on Earth. If a species goes extinct, the ecosystem will be affected. This can have bad repercussions to humanity.
Stop killing them
It is easier and quicker to save a species when it is at risk of being extinct. Speciation takes too long; therefore humans should do everything within their power to save animals.
Because it is an endangered species, and if we do not save it, it will die out, or become extinct, much like the Dodo.
be more specific about this "planet". We should save Earth because if we don't, the Earth will be messed up and we'll all die. ;( ;(
We can do various things to save planet earth from dying. Plant trees is the most viable.
Extinct species are generally considered to be permanently lost. However, there have been cases where species once thought to be extinct were rediscovered in the wild. The process of reviving extinct species through technologies like cloning is still largely theoretical and ethically complex.
Extinct is already dead and Endangered is there is less of them left in the world meaning we should try to save them !!
possibly DNA duplication and genetic research to find the genetic code of the extinct species to possibly revive them
The same reason you should save every other species from going extinct; once it's gone, it isn't coming back.
