It's the circle of life.
The circle of life is a story from the Disney film 'The Lion King'.
People buy food in shops. Gary Yourofsky points out that where animal products come from is the circle of torture and death.
We can live healthily without eating decaying flesh, so the most compassionate thing is to not pay for animals to be killed and cut up.
Other people say we have to eat animals to maintain the ecosystem. That is not true. We are currently destroying the oceans, the rainforests and polluting the air. The best practical step to reduce this is to all live a Vegan lifestyle. Supporting evidence here - http://www.bertyjustice.co.uk/vegan-for-the-envirnoment.html
