Hence it should become evident that harming or even destroying nature - i.e. our environment and basis of being - does at the very end hinder ourselves most: We harm or destroy exactly what we eventually wanted to get in unison and harmony with.
In regard of the common rude and thoughtless dealing with nature, the above may sound rather hopeless for our future. For your personal development however, only your personal behavior counts and not the behavior of "average people" or of a certain majority. It's only about you! Therefore it is possible to develop yourself when you limit your negative footprint of your life here on earth (e.g. consumption of resources, pollution of the environment) to an acceptable level. This is your contribution to solving the problem.
