My parents were worried that their divorce would have a deleterious effect on us kids, but in the end it was less harmful than watching them fight all the time. For most plants, a lack of sunlight has very deleterious consequences, but there are some plants that actually do very well in the dark. It's a wonder, given how well-established the science is, that we continue to do things that are deleterious to the fragile ecosystem. We must be willing to live with the deleterious effects.
