What a perfectly optimistic way to begin the new year, via Hampton Univeristy Professor Cuker in Dailypress.com:
Jesus shared the earth with no more than 400 million other souls, Thomas Jefferson with about 1 billion contemporaries, and at projected population growth rates, our children will live with 9 billion others by mid-century. Such rapid population growth can not go on endlessly. Humans, like all other species, can only populate up to the carrying capacity of the environment. Carrying capacity is set by availability of resources (food, water, places to live) and sometimes by the build-up of toxic metabolic wastes. However, as populations approach their carrying capacity, growth often slows as a consequence of increased mortality and lower birth rates due to disease, competition and malnutrition. And for humans we can add the scourge of wars fought for controlling limited resources.
