No idea what the policy is on plagiarizing Wikipedia
envrionment.blogspot.com/2008/10/genetic-erosion.html This page, which turned up in one of my alerts, rang a bell. It is a direct steal from here. There's probably nothing that can be done, but I thought I would draw attention to it. I'd prefer not linking to it because there is no point giving the page any credibility, but I don't how to switch automatic linking off. Maybe someone else can do that?

Hi Dont Panic
The reverse is true, the page you mention is a direct copy of wikipedia page "Genetic erosion", it should mention the source as wikepedia.

It worked: the link is gone. Simon de Danser (talk) 03:13, 15 August 2009 (UTC)
removed POV and rantish text
I just removed the following text as I have found this verbatum on several articles. Is it POV pushing? It reads like it. The fact the exact same text is in several articles explains why it does not dovetail very well into this article. i think these points are worth discussing but it neds to be rewritten to not be POV and relate directly to the subject of the article. It is way too general right now. David D. (Talk) 03:50, 12 November 2007 (UTC)
- Genetic erosion in agricultural and livestock biodiversity
- Genetic erosion in agricultural and livestock biodiversity is the loss of genetic diversity, including the loss of individual genes, and the loss of particular combinants of genes (or gene complexes) such as those manifested in locally adapted landraces of domesticated animals or plants adapted to the natural environment in which they originated. The term genetic erosion is sometimes used in a narrow sense, such as for the loss of alleles or genes, as well as more broadly, referring to the loss of varieties or even species. The major driving forces behind genetic erosion in crops are: variety replacement, land clearing, overexploitation of species, population pressure, environmental degradation, overgrazing, policy and changing agricultural systems.
- The main factor, however, is the replacement of local varieties of domestic plants and animals by high yielding or exotic varieties or species. A large number of varieties can also often be dramatically reduced when commercial varieties (including GMOs) are introduced into traditional farming systems. Many researchers believe that the main problem related to agro-ecosystem management is the general tendency towards genetic and ecological uniformity imposed by the development of modern agriculture.
- Conventional hybridization for higher yield, genetic engineering and the resulting loss of biodiversity, a threat to food security
- In agriculture and animal husbandry, green revolution popularized the use of conventional hybridization to increase yield many folds by creating "high-yielding varieties". Often the handful of breeds of plants and animals hybridized originated in developed countries and were further hybridized with local verities, in the rest of the developing world, to create high yield strains resistant to local climate and diseases. Local governments and industry since have been pushing hybridization with such zeal that several of the wild and indigenous breeds evolved locally over thousands of years having high resistance to local extremes in climate and immunity to diseases etc. have already become extinct or are in grave danger of becoming so in the near future. Due to complete disuse because of un-profitability and uncontrolled intentional, compounded with unintentional crosspollination and crossbreeding (genetic pollution) formerly huge gene pools of various wild and indigenous breeds have collapsed causing widespread genetic erosion and genetic pollution resulting in great loss in genetic diversity and biodiversity as a whole[1].
- A genetically modified organism (GMO) is an organism whose genetic material has been altered using the genetic engineering techniques generally known as recombinant DNA technology. Genetic Engineering today has become another serious and alarming cause of genetic pollution because artificially created and genetically engineered plants and animals in laboratories, which could never have evolved in nature even with conventional hybridization, can live and breed on their own and what is even more alarming interbreed with naturally evolved wild varieties. Genetically Modified (GM) crops today have become a common source for genetic pollution, not only of wild varieties but also of other domesticated varieties derived from relatively natural hybridization[2][3][4][5][6].
- It is being said that genetic erosion coupled with genetic pollution is destroying that needed unique genetic base thereby creating an unforeseen hidden crisis which will result in a severe threat to our food security for the future when diverse genetic material will cease to exist to be able to further improve or hybridize weakening food crops and livestock against more resistant diseases and climatic changes[7].
Quote?
I have removed this text? What is the point of this text? Is it a quote? Shouldn't in be paraphrased or put into some context? David D. (Talk) 04:00, 12 November 2007 (UTC)
- Processes and consequences
- “A population bottleneck creates a shrinking gene pool that leaves fewer and fewer mating partners. What are the genetic implications? The animals become part of a high stakes poker game -- with a crooked dealer. After beginning with a 52-card deck, the players wind up with, say, five cards that they are dealt over and over. As they begin to inbreed, congenital effects appear, both physical and reproductive. Often abnomral sperm increase; infertility rises; the birthrate falls. Most perilous in the long run, each animal's immune defense system is weakened. Thus, even if an endangered species in a bottleneck can withstand whatever human development may be eating away at its habitat, it still faces the threat of an epidemic that could well be fatal to the entire population.“[8]
So what is the context for this? Why do we need this long quote, can't we paraphrase it? David D. (Talk) 22:09, 16 November 2007 (UTC)
