Unnatural Selection
Documentary: Life Running Out of Control aka Unnatural Selection
This is one of the best documentaries I have seen. This explains how genetically modified plants/animals lead to suicides in Indian cotton farmers to effect of health on humans who consumed them. In US, genetically modified plant/animals products are being sold for the past eight years. Also, these products are increasing penetrating into international markets. People are increasing consuming them all over the world. In a lab test, mice were fed with genetically modified food. Scientists observed that trails of DNA of genetically modified food is seen in mice; this might eventually affects immune system of mice. On humans, the effects of genetically modified food, though may not surface now, will certainly show up in forth coming generations. Some of the genetically modified fish are escaping laboratories into wild. This leads to genetic pollution, which doesn't dilute like chemical pollution over a period of time, instead reproduce to change the ecosystem, however, bio-engineering firms claim that those fish varieties are sterile. But, God only knows what the effects are.
My question is: Is it really to be seen as genetic pollution? Or, are we catalyzing the evolution process, which otherwise would take millions of years to show the effect, naturally? However, natural evolution is factored by environment and errors (or changes) in cell mutation. But the genetic modifications we are working doesn't seem to be having environmental consideration, which makes genetically modified species difficult to survive in the wild. But, somehow, if they adapt to survive, then the human-driven evolution starts.
