Well it would be nice to go back to horse and cart but a. Horses emit methane when they fart (another greenhouse gas) everything emits something. b. Where would someone living in London put a horse and cart (applies to other cities) As for the other question heres the links. http://www.healthyea...-additives.html http://fooddemocracy...-avoid-and-why/ As for food additives I can't find the ingredients for any products of the three main supermarkets (ready meals, tinned etc) publicised anywhere. I wonder why. Neither can I find a list of the steroids, drugs, antibiotics and growth hormones they pump, cattle, sheep, chickens and pigs full of these days. The same goes for a list of permitted pesticides and herbicides that can be used on crops and fruit in Europe. And the effects they have on the human body and the environment, waterways, oceans, fish animals etc. Again I wonder why this information is so hidden. I respectfully suggest that either you look at the labels on things next time you shop or that someone with more experience in internet searches and time on their hands finds and posts the links on this thread. Naturally I also fully expect someone with a vested interest to post something saying exactly the opposite as well. After all we have not evolved in such a short time that the ingestion of so many chemicals into our bodies would not have a deleterious effect have we.
