Sorry, Vegans: Brussels Sprouts Like to Live, Too

Science has determined that plants live. They not only live, but they struggle to survive. They are aware of their environment. They communicate with other plants and animals.

So the next time a vegan or vegetarian tells you they are being kind to animals because they won't eat them, you need to ask them why they hate vegetables so much that they need to eat them!
