In ancient times when humans on the earth numbered only about 10 million, or less, they were entirely subject to capricious whims of environment and natural conditions. Floods, weather changes, volcanoes, earthquakes, wild animals, all kinds of diseases and injuries and all other external conditions foisted upon them were, nonetheless, UNthreatening to the entire species (to speak generally). Of course, a meteorite striking the earth brought about major consequences as to survival, but again that was NOT something of their own doing.
NOW, though, irrespective of the opinions of our less than "brilliant" president and his less than "sterling" appointees, there are dire results which are beginning to threaten the entire species. ONE of them that has NOT even been widely suggested is the Earth's OVER-POPULATION. If there is ONE rule that governs and applies on a rather constant basis, it is that NATURE exacts a PRICE for whatever is taken from it. We have it on very good authority now that GLOBAL WARMING results from HUMAN activity. However, what needs to be said is that HUMAN "success" in terms of population growth and expansion will also become a liability--resulting in the failure of the species.
How far into the future isn't quite clear, but there can be no doubt that the more success we have with creating lower death rates, less sickness, less mortal threats, the price will only be higher later on.
We do need our best scientific minds to begin to deal with this inevitability. SUCCESS in terms of the human species "over-coming" adversity will be PAID FOR at some time in the future. Of that simple truth, we should have no doubt.
As we have a look at some of the most recent predictions attributable to GLOBAL WARMING, do access the San Francisco Chronicle's article titled "Global Warming, Likely Man-Made, New Study Finds" ...
and then, simply work this out logically. More people on Earth means more carbon emissions. That's what HAS been and what continues to be the case. Approaching Six and a half Billion on earth now. But what about the future? "The planet's population is projected to reach 6.5 billion at 7:16 p.m. EST Saturday, according to the U.S. Census Bureau and its World Population Clock." That's tomorrow night; set your watches. Read the article in WiredNews: http://www.wired.com/news/technology/0,70238-0.html
Wars, rumors of wars, deprivations, hunger, plagues, nuclear destructions: YOU CALL IT and you'll be right.
"Each year, about 90 million new people join the human race. This is roughly equivalent to adding three Canadas or another Mexico to the world annually, a rate of growth that will swell human numbers from today's [population] to about 8.5 billion by 2025." quoted from http://dieoff.org/page120.htm with the HOME at http://dieoff.org/ But what about 2050, 2075, 3000 and beyond?
Do we imagine that the human species will renounce GREED? ... Do we delude ourselves that we WON'T have more George Bush TYPES as "leaders"?
Finally, do access information on the site that begins with "The relationship between humans and the state of the ecosystem is not only dependent upon how many people there are, but also upon what they do. When there were few people, the dominant factors controlling ecosystem state were the natural ones that have operated for millions of years. The human population has now grown so large that there are concerns that they have become a significant element in ecosystem dynamics. One of these concerns is the relationship between human activities and climate, particularly the recent observations and the predictions of global warming, beginning with the alarm sounded by W. Broecker (1975)." Found on http://members.aol.com/trajcom/private/popco2.htm
THE PENDULUM SWINGS. But, the direction it seems to be swinging is not the stuff of "STORYBOOK" lovliness.
So, just HOW WILL ALL THE NATIONS OF THE WORLD control WORLD population? At SOME POINT, this extremely DIFFICULT problem will DEMAND a solution.
