Some of my favorite quotes regarding natural consequences:
“In the law of God, there is no statute of limitations.” — Robert Lewis Stevenson, Dr. Jekyll and Mr. Hyde
“Whether we and our politicians know it or not, Nature is party to all our deals and decisions, and she has more votes, a longer memory, and a sterner sense of justice than we do.” — Wendell Berry
On the relationship between religion and environmentalism:
“We should not destroy what we can’t create. The time and energy and physical computation it took to evolve each species is unfathomable. If there is a God in any sense of the word, then He speaks through those things–and I want to listen.” — Ryan Dellana
