Why do we need to save nature?
We need to save nature in order to save other people and ourselves. Agree??
The Earth has been changing since it was formed and will continue to change long after we are gone. If humans disappeared it won't stop what has already started, it is just impossible without some technical discovery. Until then the best we can do is be as kind to the planet as possible, adapt by making necessary changes and relocations and live the best happy life as possible. Maybe in the future humans will find technical discoveries that can clean up some of our mess, but stopping the planet from changing seems like a God like act that is out of our control for the moment. Just chill out and be happy - do your best
Nowadays we are very careless about it.. We have to carefull about that and know the all awareness too keep safe the world. Remember that save nature mean save life
