A couple of points:
1. Saying man has natural rights grounded in the nature of man is the same as a pronouncement. It is an unsupportable assertion of fact which refers to itself for proof of its veracity. Circular logic at its worst.
2. To have dominion over certainly is not equal to "doing what you want with". A shepherd does have dominion but is charged with caring for and protecting the flock, and if necessary killing one of it for his survival. The notion that the creation is here for our pleasure is so absurd and revolting that to assert it offends the spirit of life itself.
