Do the Japanese really love nature more than all other people ?

[Maciamo]

I'm not certain that having differing names for males and females and the young of a species makes them more "childish and primitive" either. It would seem to be a jump in logic to make such an assumption.

Children use more simple vocabulary than adults, hence saying "female deer" because they don't know the proper word (doe) does sounds more childish. If the Japanese constantly say "male/female something" instead of having a special word for it, it consequently sounds more childish for speakers of a language which has those special words. Considered as a "society's language" (as oppose to individual knowledge of a language), the absence of such words make this language look primitive compared to other languages with more words.

I also don't know if it follows that vegetarians care more about nature than other humans.

It depends what is the reason for vegetarianism. If it is just because you don't like meat or think it is not good for health, then not necessarily. But almost all the vergetarians I know are vegetarian because they do not want to kill animals. Strict Hindus and Jains are vegetarian because their religion tells them not to kill any animal. True Jains go so far as to watch their steps in order not to crush an insect, and wear a mask in front of their mouth to be sure not to swallow a mosquito. They also prohibit anything made of leather or other products made from dead animals. You cannot enter a Jaina temple with a leather belt, wallet or shoes. Doesn't that show a greater respect for nature ? Isn't that intricately linked to their vegetarianism ? (for the record, I am not a vegetarian)
