It is not OK to sell the eggs at the farmer's market, government inspected beef from a cooler or to sell milk to your mother. The system is so regulated that small farmers are forced to do things that are illegal. Again, such laws are designed to prohibit the market from the small grower and give the market share to the large players. We know that the spread of human diseases can also be understood ecologically. Two ways that diseases are spreading in our times are by multi-partner sexual activity and by dirty hypodermic needles.
Nature is an organic whole.
Its relationships cannot be violated without consequences. These have the force of law. Nature is also full of wonder and meaning for the human person. To discover the relationships, to learn the laws of nature and to follow them is to become free. It is to choose life.
