What will be the dominant species on this planet in a few million years? A few little mammal species survived the last extinction when the dinosaurs lost their position as the top of the heap. The first dominant creatures were aquatic, then reptilian, now mammalian, and then what – insects?

            Why wonder about what will replace us? We are destroying this planet with global warming. If we can’t get it under control in the next few years most animal species won’t exist. Cockroaches have always been the presumed survivor after a nuclear war and they like warm areas.

            If we can’t cut the increase and turn it around, Earth will become superheated like Venus. Venus used to have a climate similar to ours before the volcanic activity put gases into the air. They heated the oceans putting lots of moisture into the air causing more heat to be trapped. Does that sound familiar? Our CO₂ is acting like the volcanic gases and our atmosphere is carrying an increasing amount of moisture. We call Venus’ condition “runaway global warming”. Could we be in the early stages of the same condition?

            The time to act was decades ago when the problem was easier to correct. It now will demand greater and more abrupt changes in our behavior. Are too many people and businesses more concerned with politics and greed than saving all life? Is it already too late for all life to exist in another thousand or so years?
