First of all, we should make people know that we're part of the nature no matter how we evolve. We still depend on nature. So, nature will have great effects on us in every aspect. A well preserved nature can give us a necessary enviroment for us to live and develop. Without a good nature, human cannot sustain, let alone develop. Therefore, we should mobilize everyone to do things they can in their daily life, and should demand govenrment make regulations on enviromental protection. But, most importantly, we can imporve ourselve behaviors, such as, rejecting eating wild animals, using recyclable batteries,not wasting paper etc.
