I have been vegan for 3 years and, prior to that, was vegetarian for many years. I neither eat, use nor wear animal products. My food choices are usually highlighted by other people who find me either eccentric or accusatory - even when I have said nothing. The reason I am vegan is ethical. If people had to visit a slaughterhouse, see the terror of the animals, hear the sounds and smell the blood - I wonder how many would be happy to go on eating meat? If they knew the cruelty of the dairy industry, cows raped so that they keep bearing calves and their male calves, those that are not kept for breeding, systematically either slaughtered or left to die. Whereupon the cow will call for her stolen calf for up to three months - sometimes longer. Chickens, fish - living and dying appallingly... want me to go on? Of course meat eaters don't want to know about all this - it makes them uncomfortable. It comes down to too many human beings in this word and one third of them being immensely greedy (the others subsisting at starvation level), destroying the planet's atmosphere with the methane produced by cattle and the clearing of forests to graze them. We have to rethink the size of our world population and how we feed ourselves without destroying our planet and all the species in it. If you have children, this should be of supreme importance to you. I have step-children but none of my own - and I care passionately about what is to become of us all. That is why I'm vegan.
