Bacterial Growth And Multiplication. growth and death in a bacterial population, including vocabulary and video clips. From Cells Alive. http://www.cellsalive.com/ecoli.htm
Extractions: Contact Bacteria Divide and Multiply Bacteria are all around us. Given good growing conditions, a bacterium grows slightly in size or length, a new cell wall grows through the center forming two daughter cells, each with the same genetic material as the parent cell. If the environment is optimum, the two daughter cells may divide into four in 20 minutes. Oh my! 1, 2, 4, 8, 16, 32, 64... Then why isn't the earth covered with bacteria? The primary reason may be that conditions are rarely optimum. Scientists who study bacteria try to create the optimum environment in the lab: culture medium with the necessary energy source, nutrients, pH, and temperature, in which bacteria grow predictably.

Extractions: Home About Headquarters UNEP.net ... Contact Us The African Great Lakes region is composed of a variety of ecosystems with significant biodiversity. Click on the map to take a closer look at the area. The region's relief is moderate and influenced by tectonic and volcanic activity. The highlands are relatively cool with abundant rainfall. Major drainage basins include those of the Congo-Zaire, Nile and Zambezi rivers which drain into the Atlantic Ocean, Mediterranean Sea and Indian Ocean, respectively. Forests are also dominant in the lowlands of the Congo-Zaire Basin, while grasslands and savannahs are most common in the southern and eastern highlands. The climate and rich volcanic soils in the highlands sustain intensely cultivated croplands, encouraging the growth of human population. This increased population is competing for habitat used by many endangered species, including the mountain gorilla and the forest elephant. Governments in the region are attempting to lessen the impact through integrated conservation and development projects.

Desert Invasion - U.S. - Destruction Of U.S. Border National Forests, Monuments, Focuses on the adverse effects of illegal immigration on communities, ecosystems, and parks on the US side of the border, and advocates stronger control of immigration and population growth. Articles, photos, action alerts, and links. http://www.desertinvasion.us
Extractions: New Articles The United States is being invaded across our southern border. Ranches, border towns and public lands are being overrun as danger escalates. Millions of illegal aliens and drug runners have entered into our nation because, while protecting the borders of countries half way around the world, the most powerful nation on earth lacks the political will to protect our own borders. Neither of the two major political parties care about the future of our country. Republican constituents profit from the cheap labor that illegal immigration brings. Democrats seek to bolster their party with votes from the immigrant bloc. Even though poll after poll shows the vast majority of Americans want their borders protected, Congress refuses to adequately address the illegal immigration invasion and to adequately fund measures to protect our border. Why the tidal wave? Our fragile National Monuments, National Wildlife Refuges, National Parks, and National Forests along the U.S. southern border are being annihilated - not by natural forces or by unwitting tourists, but instead by an overwhelming number of illegal aliens (up to in Organ Pipe National Monument alone in recent years) who rampage through and destroy these supposedly protected areas. Our beautiful and pristine areas, set aside by Congress to preserve for future generations, are quickly being turned into

Bio52: Population Growth Our interest in human population growth was sparked by the numerous Currently theworld s popultion is increasing at an almost exponential rate. http://www.cs.hmc.edu/~belgin/Population/
Extractions: This page is the product of a Biology project for Harvey Mudd College, a small science and engineering school in Southern California. Our interest in human population growth was sparked by the numerous articles we uncovered on the subject as well as our innate interest in the future of humanity. We hope you find the following information useful and accessible. Enjoy! Before perusing this page we would like to ask that you just take a look at the world's current population as projected by the U.S. Census Bureau. Think about what the population was 350 years ago: about 500 million. What sorts of things could cause such a great increase? And if this continues, how high could the population rise? Can the Earth support these levels of population? Currently the world's popultion is increasing at an almost exponential rate. This has lead to a heightened interest in the feilds of demographics and population dynamics; we have compiled some relevant statistics for your perusal.
The Myth Of : John McCarthy's Sustainable Progress Short article by Rupert Edwards arguing against McCarthy's premises regarding nuclear power, population growth and living standards, and definition of progress. http://www.geocities.com/RainForest/Canopy/2265/no_prog.htm
Extractions: or the Dream-on Prophets of Techno Nirvana. The various ecological chicken-littles maybe correct or incorrect about any particular issue, but I'm most concerned that so little is done to fix problems before they become disasters. The business as usual always seems to want to avoid thinking about, thence taking responsibility for action leaving it to other folks to clean up the mess, if there is still time! Like on 'Peak Oil' where Richard Heinberg in his webpage The Petroleum Plateau" ( MuseLetter No. 135 - May 2003) cautions;- "[thermal depolymerization].. assumed to be - a means to maintain business as usual, it could in effect not be a good thing at all. Much the same could be said of hydrogen fuel cells, cold fusion, tar sands, and dozens of other recent or potential energy innovations, as well as "sustainable development" and the various business greenwashing initiatives. Whether they are useful strategies or mere distractions preventing us from grasping the essential nature of our dilemma and undertaking the hard choices" The Myth of : John McCarthy's Sustainable Progress Critiqued by Rupert Edwards This page is a condensed rebuttal of the unsustainable flights of fancy of the cornucopian scientific propaganda, that believe business as usual with no-holds-bar technology will eventually save the Earth for those that matter. Probably the most dangerous thing on the infobahn propagating this delusion are John McCarthy's web-pages about "Progress And Its Sustainability". John lectures on the 'sustainability of progress' while researching the technological opportunities for humanity at Stanford University. John definitely is one smart dude and I have a lot of respect for his work in
Thomas Malthus & Population - 200 Years Later A celebration of the 200th anniversary of Thomas Malthus' Essay on the Principle of population by the group Negative population growth. Audio, news stories, conference, and the original essay. http://www.npg.org/projects/malthus/malthus_index.htm
Extractions: T he 200th Anniversary of one of the most provocative essays in the history of Western thought is upon us, the original edition of An Essay on the Principle of Population by Thomas Malthus, first published in 1798. This important essay first identified the geometric role of natural population increase in outrunning subsistence food supplies, prompting Charles Darwin to explore the actual patterns of evolution. What can we learn from Malthus 200 years later? Approximately one billion people now go to bed hungry every night. Several hundred thousand die of malnutrition every year. Malthus recognized limits: can we ignore population limits in today's world?

Extractions: e-mail group Human Population Growth and Migration have serious consequences, globally and for the United Kingdom Population Growth, Natural Increase and Migration Population growth is primarily caused by natural increase , that is, the excess of births over deaths. But in any particular region, migration will cause population growth when the amount of immigration exceeds the amount of emigration . And in the United Kingdom at present, migration is a greater cause of population growth than natural increase. Both population growth and migration can affect the quality of the natural environment, the likelihood of conflict, and social cohesion between ethnic groups. In our view, the significance of both population growth and migration are often underestimated by governments and non-governmental organisations. Population Growth and Migration: Global Aspects At the global level, human population growth is one significant cause of environmental problems - destruction of natural ecosystems, increased rate of species extinction, soil erosion, falling water tables and depletion of aquifers, pollution of rivers, seas and coastal waters, increase of harmful emissions to the atmosphere. Population growth has in our view, already taken the human population beyond the carrying capacity of the planet. Through its adverse effect on the environment, population growth is a significant cause of the increase in the number of environmental refugees (people who can no longer secure a livelihood in their own area because of environmental problems such as desertification). The number of environmental refugees will be greatly inflated if, as expected, global warming causes sea levels to rise, inundating vast areas of densely populated land. In the past, abrupt climate temperature changes have occurred. If they occur in the future, agricultural systems may be unable to adapt fast enough, causing massive decrease in food production, which in turn will swell the number of environmental refugees. Environmental refugees may simply be displaced within a country, or they may by international migration move between nations or continents. Such disruptive movements can impede attempts to achieve sustainable development.
