I agree with you @sean-king, nature plays a very significant role in the development of a person. Everything that a person have comes from nature which were given of course by the creator. Knowledge, wealth, health, connection they all came from nature and most of the people are forgetting or maybe they just don't know. This possibility could be the reason why the human population doesn't care much of the environment.
Environment is deteriorating and its so hard nowadays to convince anybody not to turn their back from environment. Instead of convincing other people, best thing to do is to convince 1 person and that is ourself. I can't find a reason why we couldn't convince ourselves.
Lets take care of the environment and lets start it within ourselves.
