Well not depleted, matter is never destroyed...converted surely, our continued population growth will insure that....as does any population, until it reaches a density to which it can no longer survive, fairly natural actually.not sure what you mean here wil...?
Lacto-vegetarian if you insist!So I don't take supplements of the kind you mention. Why stop at oceans? Planet earth is being depleted, courtesy of man IMHO.
What I was getting at is we all have our lines...you've drawn yours it appears as that you don't eat dead animal flesh, but are a member of the only species that drinks milk (cheese, dairy) cross species, and continues drinking it after its weaned and a product that is designed to increase the weight of its species to 300 pounds in six months. I'm not being judgemental here...I've been known to consume cheese and yogurt to my mucous creating detriment.
Now most lactos also consume chicken embryos and honey....again not judgemental just identifying the line, that somehow we feel it not right to eat the flesh of the chicken...but we've got sort of a prochoice attitude goin....and many of us also don't like mistreatment of animals but don't seem to have issues stealing the nutrients required for healthy growth of bees (honey) and replacing it with sugar water....the substance many veggies refer to as white death and wouldn't wish on our enemies....
We all have our justifications....even Jaines don't wait for the fruit to fall in their hands...
Bottom line though is we are all part of the animal kingdom....we live on this planet and we consume to live...some of us just live a little better and with less conscience...
