Over the past few decades we've all become increasingly concerned with preserving and protecting the natural environment in which we live and upon which we must survive. Ecology has entered our vocabulary. We know now about rain forests, the ozone layer, global warming, and the toxic effluents generated by our means of production.
Pollution is a terrible reality.
We know, too, about our terrible rate of consumption of the world's natural resources. A lot of evils and human suffering result from the way we live. Living in a clean world involves more than simply what we're doing to the material creation God has given us. Living in a clean world also involves the spiritual nature God has likewise given us, what we call the soul. The soul is something that will last forever - it will never die.
