Jay Lehr, Ph.D. Science Director at The Heartland Institute: Many science and technology institutions and local and national governments use the term carbon to mean carbon dioxide. They refer to a person's, company's or country's "carbon footprint." Carbon brings to mind dirty carbon soot, not the colorless, odorless gas of life, carbon dioxide, which is what is really meant. Dr. Lehr explains the reason for this deliberate deception. It is like the deception of man-made global warming being called "climate change." Some countries don't tolerate this misuse of science. They will have far better energy programs and be in positions to take advantage of every weakness the "carbon footprint" using countries have. It is a shame to see North America and Europe allowing this to happen.
