We still have people among us who believe climate change is a hoax or some sort of natural cycle of the Earth, despite overwhelming and unrelenting evidence to the contrary. Another brick in the wall of reality was put in place this week with the release of a federal study showing that nearly half of the lakes and reservoirs across our country contain fish with potentially harmful levels of mercury, a metal that is toxic to us humans. An AP story notes that mercury is a pollutant "primarily released from coal-fired power plants." Coal is a valuable fuel resource in our country, and the industry is a provider of a great many jobs in this area, but it galls me that when someone suggests that we need to do more to control emissions from coal-fired power plants - at some additional cost to consumers - the climate change deniers and energy industry apologists start shrieking as if their hair were on fire. The new EPA study on lake and reservoir pollution is yet one more sign that we need to quit poisoning the world in which we live. It amazes me that with all the technological advances and brilliant minds we have in this country, we are still burning rocks for fuel, but if we are going to do so – and we clearly are for at least decades to come – we must find ways that do not kill us in the process.
