This, however, may not be necessary, since humans seem to be racing to see if they can save Her the trouble. They behave so arrogantly, contending they are superior to Nature. Rain forests are being cut down or burned—not only polluting the air but also causing a drop in oxygen levels. The love affair people have with their automobiles, especially “gas hog” SUV’s, adds to the pollutants in the air and is, yet, another nail in their coffins. Since prehistoric times, humans have been stalking and killing animals, causing many, beginning with the mastodon and sabertoothed tiger, to bee extinct.

Even more disturbing is the fact that, due to largescale cutting, the famous cedars of Lebanon, mentioned in the Bible, no longer exist. Along the same lines, so much of the rain forest in Panama is being destroyed that scientists are predicting the Panama Canal could fill with silt, thus prohibiting ships from crossing the isthmus, due to the effects of deforestation.Deforestation and erosion, along with changing weather patterns, have led to the fastestgrowing regions on this planet—deserts. All the while, populations are exploding worldwide and the proliferation
