You are out with your child in a field of beautiful flowers, you ask the child what purpose the flowers
serve. The child tell you that one of the techers has told the class that the flowers are there to make it pretty for us humans, so we can enjoy their beauty. A very nice thought but oh so hopeless and incorrect.
Much of our culture which are quite colored by the Bible, have caused an extremely humanocentric view. We have a long history of putting mankind foremost in our way of thinking. This has even gone to such extremes as thinking the earth was the center of everythimg, the sun, the moon and the stars was there for us, all animals, plants etc are here for us. Just remember the flood myth what God said to Noah and his family about the earth, the animals etc.
Of course there was quite an uproar when science pointed out that the earth was revolving around the sun. That was a very dangerous undertaking as it dealt a serious blow to the idea of the earth being the center of things. Science has chipped away at this worldview ever since.
Of course nothing around us are here for us. It is just here because the earths environment make such a diversity of different life possible. Here is the right conditions for life to thrive. The sky isn't blue so we should think it is pretty, everything in nature that we find pleasing and beautiful isn't there for that purpose. The animals aren't here for us, they are not ours although we kill and eat them as they do among themselves.
The humanocentric way of seeing everything around us that we share this planet with has caused much harm both to the environent and to many animal species and continues to do so. There is little humbleness in such a view.
But this way of thinking is so ingrained in us that it is extremely hard to think otherwise. I think we all need to ponder such questions much more then we do today.
