Genetically Modified Anything
A recent Science Weekly Podcast: The God Species by Mark Lynas , caught my attention.
Mark Lynas appears to be a ďgreenĒ activist who has achieved a startling degree of moderation.
In the interview he discusses Nuclear energy (vs. fossil fuels) and Genetically Modified Crops.
For several years now I have seen the Genetically-Modified -scare as equivalent to the Global-Warning-scare, because they share the same foundations.
Disclaimer: This blog is about Clear Thinking, so relax your mind for a moment.
About 11,000 years ago the earth came out of an ice-age Ė erroneously called ďThe Last Ice AgeĒ, but more correctly called ďThe Latest Ice AgeĒ. The Great Wisconsin Ice Sheet began to melt, a single example of a process duplicated all around the world. Humans began cultivating crops and, as Isaac Asimov pointed out, that led to civilization and the need to protect assets; hence war.
So for the past 11,000 years the earth has been in a warming trend. Globally.
Donít let the two words ďGlobal WarmingĒ scare you. The earth has been getting warmer for 11,000 years, and it started long before gas-guzzling SUVs came on the market.
Humans began harvesting seeds from grasses, perhaps carrying a few seeds with them and planting them in new ground as populations grew and young marrieds moved out to the suburbs. Yes, it was happening 11,000 years ago!
Some crops would do better than others. Perhaps your seeds came from a slightly different region than mine, so hey! Can I have some of your seeds please?
With very little science at hand, humans accidentally (?) selected seeds from those crops that gave high yields, and ignored seeds from crops with low yield.
Nothing new here. Darwin said it all. But humans were now accelerating evolution by aiding natural selection with un-natural selection (unless like me you consider humans to be a perfectly natural outcome of natural selection).
The bread you eat today comes from wheat that, one hundred years ago, was wheat that had been selected over thousands of years.
Our ancestors practiced genetic modification, through seed selection, and thatís how your great-grandmother, grandmother and mother ate bread.
Everything we eat today has been modified genetically. Itís only in the last 20 years or so that humans donned white coats to do the deed, and have accelerated the process by using chemistry to splice stuff.
If you want something to worry about, worry not about genetically Modified crops (and animals).
Worry instead about Bio-Diversity; with your friends and your local members of parliament discuss the impact of humans becoming reliant on just a half-dozen strains of wheat, on just a half-dozen strains of corn, on just a half-dozen strains of cattle.
Consider a world with only six breeds of dogs, including work- and pet-dogs.
How do you feel about that?
