Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

Elizabeth Alter is an assistant professor of biology at City University of New York College............She accurately makes the case that we are "knee-deep" creating into the so-called "Frankenstein"-like" organisms via genetic engineering.that have no natural control agents in nature............The "checks & balances" of the natural world created through billions of years of evolution are being undone in our business, education and science labs on a daily basis...........And of course, just like with pesticides, solvents, plastics and food additives, we humans are touting all as advancements and enhancements to our lives, simultaneously getting poisoned and adversely impacted by their currently harmful(and potentially harmful) side effects........As Elizabeth so aptly states: "Researchers can cut and paste DNA into just about any animal, plant or fungus".......... "Whereas modified genes were once likely to be stamped out if by chance they made it into the wild, today’s technologies can supercharge a genetic chain reaction".........: "A technique called “gene drive” ensures a modified gene will be inherited with nearly 100 percent success"............ "This is valuable in making sure that a desirable new gene, like one resistant to the malaria parasite, spreads once introduced into a mosquito population"........... "It also means a mistake can’t easily be taken back".............."Genes could potentially leak to places where these species actually play important ecological roles — and could even jump to other species through interbreeding"................. "Re-engineered genes that escape from crop weeds and spread as a result of gene drive could devastate other ecosystems"................. "Moreover, our understanding of how genomes function is still far from the point where we can change genes and be certain we aren’t creating bigger unintended consequences".,d.eWE
