Copenhagen Fails - Omits Discussion of Population

Previous studies on the determinants of carbon dioxide emissions have primarily focused on the
role of affluence. The impact of population growth on carbon dioxide emissions has received less attention.
A new paper takes a step forward providing such empirical evidence, using a data set of 93 countries for the
period of 1975-1996. The paper has following findings. (1) Population growth has been one of the major
driving forces behind increasing carbon dioxide emissions worldwide over the last two decades. It is
estimated that half of increase in emissions by 2025 will be contributed by future population growth alone.
(2) Rising income levels have been associated with a monotonically upward shift in emissions.

Thus, without increasing costs dramatically by imposing strict controls on emissions, much could be accomplished by just stabilizing our population.

Too Many People Part VII

A full 75% of the loss of global forests occurred in the 20^th century and there are signs that this rapid deforestation is continuing. Not only has the rising population created a greater total demand for forest products but the per capita global use of paper and paperboard has nearly tripled since 1961. The loss of forest areas reduces habitat for wildlife and carbon storage which is key to regulating climate. Moreover, the loss of forest areas compromises erosion control, the provision of water across rainy and dry seasons, and the regulation of rainfall. We live amid the greatest extinction of plant and animal life since the dinosaurs disappeared 65 million years ago. The principal cause is habitat loss driven by excessive population growth. The environmental threat comes from both the wealthiest billion people, who consume the most and generate the most waste, and from the poorest billion, who may damage their meager resource base in their daily struggle to survive.

Climate change is much on the minds of many scientists. Over the last half century, carbon emissions from fossil-fuel burning expanded at nearly twice the rate of population growth, boosting atmospheric concentrations of carbon dioxide, the principal greenhouse gas, by 30% over pre-industrial periods. Emissions from developing countries will nearly quadruple over the next half century, while those from industrial nations will increase by 30%. Former Senator and Democrat Presidential candidate Al Gore’s excellent fact-filled presentation on the subject of global warming runs entirely counter to any idea that population is not a problem. The UN estimates conservatively that America produces 20 metric tons of pollutants per capita annually. If America's population increases by 300 million by the end of this century, an additional six billion tons of pollutants will be produced per year at the present rate. Even if by some technological miracle we were to be able to cut our per capita output in half to that of Mexico, we would have made no progress on reducing the present unacceptable total output.
