Introduction
Worries about human population growth are not a new phenomenon. A little over 200 years ago (1798) Thomas Malthus published An Essay on the Principle of Population. He identified the fact that the human population expansion was outpacing the production of food.
In 1804 the human population of Earth reached 1 billion, it topped 2 billion by 1927, 3 billion by 1959, 4 billion in 1972 and 5 billion by the late 1980's. On October 12th 1999, the human population of Earth reached 6 billion.
Prior to 1950, the death rate was high, which kept the numbers of humans from increasing rapidly. In the 19th Century, the agricultural revolution increased food production and the industrial revolution improved methods of transporting food and other goods. The 20th Century produced advances in medicine, sanitation and nutrition.
The rapid growth of the world population has led to increased demand of Earth's resources, many of which are being consumed at rates faster than they can be replenished. One hectare (100 acres, 10,000 square meters) of tropical rainforest can be demolished in under an hour, but it takes over thirty years for that same area to regenerate.

Quote 1. If the world is to save any part of its resources for the future, it must reduce not only consumption but the number of consumers."
-- B.F. Skinner (Intro. to Walden Two, 1976 edition)
)
Quote 2. Unlike plagues of the dark ages or contemporary diseases we do not understand, the modern plague of overpopulation is soluble by means we have discovered and with resources we posses. What is lacking is not sufficient knowledge of the solution but universal consciousness of the gravity of the problem and education of the billions who are its victim."
--Martin Luther King, Jr.
Quote 3. "The key problem facing humanity in the coming century is how to bring a better quality of life -- for 8 billion or more people -- without wrecking the environment entirely in the attempt."
--Edward O. Wilson
