Homo sapiens sapiens is the single largest species on earth in terms of biomass. We have had the greatest ecological impact on earth compared to any other species in existence in natural earth history. Through our technology and culture, we have magnified these effects exponentially. No one really knows the exact size of the human population, though realistic and conservative estimates put it at somewhere around 6.5 to 7 billion people. Official statistics from nation-state governments are often skewed, under-reported, falsified and inaccurate. Ethnographic evidence from some of the most densely populous regions suggests that the actual human numbers may be greater than 7 billion. The bottom line is that no one really knows the true size of the human population at the beginning of the 21st Century. This problem indicates a common lack of responsibility on the part of many governments to deal with this central issue in any but a token manner. Population in the United States, one of the most developed nations, has lost its zero-growth equilibrium of the early 1970's and has swelled as the result of irresponsible social policies and poor planning in an uncontrollable rate in the last three decades to emerge as the third largest in the World behind China and India. The problem of the rapidly increasing human populations figures centrally and strategically in the impending dilemmas that humankind shall face in the 21st Century. It is a basic issue that drives many other problems of human health, social-environmental circumscription and pollution, poverty and underdevelopment.
