You wouldve probably learnt in science class about food chains and how each one of them always begins with a producer, then primary consumer, secondary consumer and so on. Now for those of you who are vegetarians, you are breaking the food chain early as you feed directly on the producers. This means there is less food available for the consumers lower down the order. Doesnt that mean youre harming the delicate balance of our ecosystem more than non-vegetarians? :P Do you feel guilt ridden now? LOL Omnivores, you may chip in with your thoughts too...
