I am simply interested to know the population at hte year 1 AD and the basis of this projection. would you please be kind to narrate in simplest term.
war time in order to control so many under so few
If human population dynamics is essentially common to the population dynamics of other species and, consequently, if food supply is the independent not the dependent variable in the relationship between food and population, then a lot of what has been reported could be distractions that serve to dismiss rather than disclose vital but unwelcome science of what could somehow be real regarding the human population and, more importantly, why our behavior is so utterly destructive of everything we claim to be protecting and preserving. May I make a request? Could we focus now, here, on whether or not human exceptionalism applies to its population dynamics alone or is the dynamics of all species, including human beings, similar? Whatever your response, please make reference to scientific research that supports your point of view.
It seems to me that if we keep engaging in and hotly pursuing worldwide overproduction, overconsumption and overpopulation activities, distinctly human activities that cannot be sustained much longer on a planet with size, composition and ecology of Earth, then the human species is a clear and present danger on our watch to future human well being, life as we know it, and environmental health. If we can see ourselves to be ‘the problem’, then it is incumbent upon us to bring forward the best available evidence from science, especially when that evidence happens to relate directly to why we are pursuing a soon to become, patently unsustainable (superhigh)way of life. A tip of the hat is due Rachel Carson for making me aware of the superhighway. Should humankind emerge from ‘the bottleneck’ E.O. Wilson imagines for us in the future and somehow escape the precipitation of our near-term extinction, how are those survivors to organize life sustainably and not repeat the mistakes we are making now… and have been making for a long time? Without knowledge of why we are doing what we are doing, every one of us is forever trapped in an eternal recurrence of unsustainable life cycles, I suppose.
Sincerely yours,
Steve Salmony
PS: Rachel Carson’s quote,
We stand now where two roads diverge. But unlike the roads in Robert Frost’s familiar poem, they are not equally fair. The road we have long been traveling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end lies disaster. The other fork of the road—the one “less traveled by”—offers our last, our only chance to reach a destination that assures the preservation of the earth.
Rachel Carson (1907 – 1964)
In response to Dame Jane Goodall…
Yes, hope is vital. But so is being intellectually honest and morally courageous enough to speak out loudly, clearly and often about what is real, according to the lights and science we possess. We cannot make a difference that makes a difference if we continue not to question the ubiquitously broadcasted delusions by the world leaders of my generation who are leading our youth down a ‘primrose path’ to surely precipitate the utter extirpation of global biodiversity, the irreversible degradation of Earth’s environs, the reckless dissipation of its limited resources and the destruction of life as we know it. The very thing our leaders claim to be protecting and preserving for children everywhere and coming generations.
“The greatest danger to our planet is that we lose hope – especially if our youth loses hope. Because, if we have no hope, we give up and stop trying to do our bit to make a difference.” – Dr. Jane Goodall
what about the popular of 0 AD?
The population trends are interesting! Especially the population increase in the 20 th century and projections into the 21 st century and 22 nd century! And the haves and have not like the lower, middle and upper classes!
There has to be more equality on planet Earth! And better treatment of people, animals and plants everywhere too!
Ur incoherent or a genious. The planet needs more freedom. Equality means we are all poor.
The population trends is a complex issue it is really linked to the food supply, the land issues and the problems linked to consumption, development and limited resources! Human beings must learn to share this planet with God’s creatures and not exploit any of them! The market system of capitalism places profit above people and believes in competition instead of cooperation! This is the wrong approach! Communism is also wrong; I believe that the only way to live in a sane world is through love, peace, justice and sharing and above all try to live in the practices of democratic socialism; in order that the masses of people get what they want; that is have their needs satisfied! The human population can be stabilized to save and be in equilibrium with the environment and the ecology of planet Earth and its precious life forms and ecology whatever it takes for the benefit of all mankind into the future!
