Animals make people happy, it's a proven fact of life. People who have dogs are proven to be healthier, happier people. In America, a care home introduced cats, dogs and 100 birds for the elderly residents to look after and it possibly saved some of their lives. A man who had given up on life was drawn back into the world by a pair of parakeets. Animals are also a cornerstone of the food system, helping to provide eggs, milk, yoghurt, cheese, meat, leather and lots more besides, something the little people of the world need to learn if they're going to understand where their food comes from in the future.
