Well, you can object to Masa's calling humans the greatest race, but if you strip the word "great" of the moral content and purely look at achievement, he's right. No other species has been able to adapt its environment to it's need in the way humans have, most other animals (excluding some insect specieses) have to adapt fully to their environment.
Secondly, I don't see in Masa's post anything that points to his supporting abuse of animals. He does say "use to a certain point" and later points out that he objects to molesting and torturing animals. While the choice of words might be poor, the basic ideas are, as far as I can see, not really that far out.
And if a threat is to come from the animal world, I frankly see it not coming from mammals or other vertebrates. They have shown no skills in adapting their environment and shaping it to their needs. If we have to watch out for anyone it's the little buggers within the Hymenoptera & Isoptera
.
Thats wasps, bees & ants on the one hand and termites on the other hand. "social" insects
