Humans are most likely the reason why species become endangered, and it is their responsibility to help fix the problem. Causing a species to become exticnt has serious consequences on the ecosystem, yet we continue to perpetuate the problems that cause this to happen each and every day. We need to stop.
Humans, the environment, and nature itself kills off species after any event in time. Those animal's places will be replaced after a time as well, but during that shift humans would suffer. Like bees for example, if bees leave or die off in an area that grows any sort of pollinating plant it has a negative effect on the people whose lives depended on that food. People who worked for or on farms would lose their jobs, people that need a personal garden to afford to eat would go hungry, and all the people in between would also feel some sort of effect. The same goes for hunting or fishing till the point that a species can't replace their members or the members are effected by the resulting inbreeding need to keep their species going. Sooner or later people would feel the effects.
Since the dawn of time, many species have come and gone from the Earth. Some species die through natural means and some species are displaced from their habitats or hunted to extinction. Although humanity wasn't advanced enough to save the dodo bird or the dinosaur, humans are now able to recognize that even small, seemingly insignificant creatures play a big role in the survival of the planet. I believe that humans should get involved in saving dying species because saving animals from extinction may also one day save man.
We're often the cause of or a huge contributor to endangerment or extinction. We cut down trees, produce greehouse gasses which impact the polar ice caps etc. So we should get involved and do what we can to help endangered animals before they become extinct. Animals have as much right to their habitats as we do to use ours.
Human beings have, directly and indirectly, contributed to the extermination of thousands of different species of animals over the years. Therefore it should be considered our responsibility to prevent the dying out of any more animal species. Not only is it the moral thing to do but it also enhances the vibrancy of our extraordinarily diverse wildlife.
People make it like the animals life is in danger for going instinct or how ever you spell it, But why I say no is because no one wants things to change species come and go for a reason we wouldn't even have the animals we have today if that didn't happen because we wouldn't have bears and wolves and many other animals including us if TREX was still here the world and animals have to change
