Frankly, I have not looked into how environmentally unfriendly growing rapeseed oil is...I have only thought the opposite because it grows locally.

I have heard that soya has resulted in a lot of slash-and-burn of virgin forest in South America.

Thanks, SRS, but to again be frank, I don't like halal or kosher due to the cruelty involved - even though I majored in anthropology, I think some customs should be outlawed by the UN.

Some anthropologists would rationalise that you have to take a part/whole approach etc. - I hate such unnecessary suffering, as suggested in my poem from WalkaboutsVerse "A Good Life"
