God did in fact give us this world, and we do have a responsibility to use that gift wisely. However the world is not, nor was ever intended, to be a museum piece.

The world is ours to use, to multiply our gifts and ultimately extol the value of God. Sitting around in mud huts being ravaged by disease is a very very poor use of Gods gift. The development of cities, agriculture and all other technologies are ultimately good as so far as they reduce human suffering.

The worship of nature is a dead end. No doubt you picked up the anti-human feelings from the TV documentary, because thats the intended idea. The secularist want to lower man to just another animal. Snail, rat, man.

But the poor state of the world you see around you is precisely the effects of that thinking. When the human soul is degraded to the point that there is no soul at all, and only a mammal exist...well why not imprison, farm, subdue, and cull them?

The point of this life is to make the world a better place than we found it (and that includes the environment). The work of our hands should be to reduce suffering, build things which enrich us spiritually, and ultimately bring us closer to God. Nature will never be respected to the degree that God intended as long as we humans continue to see ourselves with such degradation.
