The world and all it contains is a gift from the Creator. to squander the world and its resources, or to fail to share it with ALL creatures is an insult to the giver of the gift.
Imagine if a friend gave you a gift. Of course, it is a gift, and you are free to do with it what you will.
In front of the givers’ eyes, you trash the gift. Is that an insult to the giver?
