regarding fish feeling pain-i have not yet heard of any evidence from anyone other than animal rights groups. just because he has a white coat doesnt mean he is correct. as an example i take monsanto scientists.
to convince me, i need to hear it from other sources. not saying its not true, but when only one group is claiming something, only fool rush in.
i fish whenever i can spare time from the garden (forest). i mainly fish for meat, but sport does definateley come into it. its fun to catch a mighty big flathead and release it if its a big old breeder.
saying that i have read a lot of opinions on this issue, both from highly motivated sources.
i dont beleive fish feel pain the same way. they feel it as a trigger for flight or fight responses.
but if it turns out they do feel pain, are the insects next? good luck with that one.

meat based diets from what i have learned are generally unhealthy for westerners. lots of peoples on earth ate nearly exclusive meat diets, but their lifestlyes had evolved with the diet, and the excercise required to procure the feed compensated.

environmentaly meat is a highly inefficient way to "manufacture" protein. the water, land and other resources required means the earths carrying capacity is greatly reduced, and issues like starving 3rd world are compounded.

vegetarianism is the only way the human race will survive poputation blow-out, if indeed the war-famine-disease complex doesnt get us first.

there was an earlier comment about organics only being pesticide free if grown in controlled environments. this certainly helps but is far from gospel.
bio-diversity the the key with agriculture and diet.
remember giant forests grow themselves. they are not fed. they are not watered. seeds are not collected and germinated and planted.

the incorporation of natural cycles and systems is essential in agriculture.
plants have their own immune system. if it is healthy, the plant will not succumb to pest and disease attack. when they are sprayed, it has been noted (by various sources i add hehe) that the production of immunity boosting compounds is reduced.
these are the compounds our own immune system needs to be fed to maintain it.
ever noticed the same companies that make our food sick with chemicals are the same ones that then give us pharmaceuticals to "cure" our ills?

you are what you eat. if you eat chemical dependent food, chances are you will become chemically dependent.
this cycle is easily broken by removing, particulary chlorine based pesticides and herbicides. hormones in animal feed cannot help either.

and heres some food for though;
what other mammal ingests milk after infacy?
what other mammal ingests the milk of other species after infancy?
