Les calamités de population dan les environnements principalement vacants. Cette présentation introduira trois exemples classiques et catastrophiques de désastres de population aux petites fractions d'un seuils de pourcent: (1) Dans les éruptions de rouge-marée dans les organismes marins unicellulaires, (2) Deux fois dans les études de renne (les mammifères), et (3) peut-être à la première population d'humains qui vit sur l'Ile de Pâques.

For the forthcoming Rio + 20 conference. Population, overpopulation, carrying capacity, and planetary boundaries. How our instinctive "VAST OPEN-SPACE" suppositions may be about to carry the whole of humankind, civilization, and earth's biosphere beyond carrying capacity thresholds and tipping points that should not be transgressed. This article QUANTIFIES three separate and classical examples of population-environment catastrophes and mass die-offs in environments that VISUALLY APPEARED TO REMAIN ALMOST ENTIRELY EMPTY (99.998% unoccupied).

The factor that makes today's generation of "under-20s" the single MOST POWERFUL generation (at such a young age) in the history of our species. Population momentum that could carry the whole of humankind to 15.8 billion worldwide by the end of this century? That is population momentum - on steroids. What is the recipe for such momentum? Half of a classical recipe is an enormous portion of the population that is less than 20 years old (which is already 50% throughout many of the world's poorest and least-developed nations). Note that members of this enormously large generation are now beginning to approach their 20th birthdays... and their childbearing years. The other half of the recipe involves very high fertility rates. What happens if this rising generation follows, on average, exactly the same fertility decisions and pathways that currently prevail in their nations?

Half of Africa's population is under twenty years old, and since they will soon be marrying and entering their child-bearing years, their fertility decisions or non-decisions will have potentially profound implications for their countries, their environment, their children, and their continent. How large might the continent's population become between now and the end of this century? This short article looks at two articles by former U.N. Population Division Director Joseph Chamie and the unsettingly power of population momentum. Recommended reading for Africa's citizens, policymakers, and leaders everywhere.

Consider this: If we take a wet paper towel and wipe it across the surface of a 50 cm model globe, the thin film of water that it leaves behind would be TOO DEEP to proportionally depict the average depth of earth's oceans and seas. And in a similar way, earth's atmosphere is another thin and fragile surface film that is far more...

Consider this: If we take a wet paper towel and wipe it across the surface of a 50 cm model globe, the thin film of water that it leaves behind would be TOO DEEP to proportionally depict the average depth of earth's oceans and seas. And in a similar way, earth's atmosphere is another thin and fragile surface film that is far more vulnerable to our disruption that we tend to imagine. These are critically-important understandings if we are to correctly appraise the Razor-Thin Surface Films that make up our planet's atmosphere, oceans, and seas. This is "PowerPoint 4" in our "Biospherics Literacy 101" collection and is made available courtesy of The Wecskaop Project (What Every Citizen Should Know About Our Planet).

In a few months, late in 2011, humanity's worldwide population will reach seven billion (FIVE additional billions added just since 1930) - and we will keep right on growing -toward eight billion in 2024 and nine billion in 2041 and, according to the U.N.'s latest estimates, toward ten billion by century's end (and even toward fifteen...

In a few months, late in 2011, humanity's worldwide population will reach seven billion (FIVE additional billions added just since 1930) - and we will keep right on growing -toward eight billion in 2024 and nine billion in 2041 and, according to the U.N.'s latest estimates, toward ten billion by century's end (and even toward fifteen billion according to the high estimates). This document critiques the book that accompanied the arrival of our sixth billion in late 1999.

This article focuses on recent research into LIFE-EXTENSION and longevity. Implications for population, demographics, and earth's biospheric machinery. Do you remember the Wright brothers? In 1903 they flew the first-heavier-than-air vehicle for TWELVE seconds and a distance of 120 feet. Then, less than seven decades later, U.S. astronauts traveled to the moon, landed on its surface, returned to orbit, and returned safely to earth in just over one week. Think of DNA, or computers, or communication which have all shown the same pattern: Discovery and an initial advance, followed by wide proliferation and technical advances. Now contemplate research into LIFE-EXTENSION. Scientists have already achieved SIX-FOLD life extensions in laboratory organisms (a similar extension in humans would result in healthy, active 500 year olds) AND have grown replacement organs from adult stem cells. And several years ago University of Cambridge geneticist Aubrey de Grey suggested that the firs
