The Conclusion.
In conclusion, endangered species and extinction is a very big issue we are facing in our world. We have been facing this issue for hundreds of years and it has still not been fixed yet. Lots of animals are endangered or have already gone extinct. This is affecting our environment and food chains because when one species is gone it affects other species. Things like habitat destruction, climate change, invasive species, or a change in population are affecting the population in different species. This is tragic and depressing because these species are affecting our future as well. They affect the medicine we could be using to cure fatal and serious diseases.
