"The fact is, it is virtually impossible to even conceive of a testing procedure to assess the health effects of genetically engineered foods when introduced into the food chain" 
-Dr. Richard Lacey, Microbiologist, M.D.

Modern biotechnology is quite different from traditional plant breeding.

One important difference lies in the fact that traditional plant breeding occurs between sexually compatible organisms.  Sexual compatibility is evolution's means of ensuring that reproduction occurs between sufficiently similar organisms.

If it didn't, if any life form could reproduce with any other, an ecosystem could never develop.  There would be no stability so specific roles for organisms within ecosystems could never evolve.

By creating a multitude of new organisms, genetic engineers run the risk of destabilizing ecosystems.  This is very dangerous because ecosystems are our life support systems, cleaning the air that we breathe and the water we drink.

What can you do to stop the spread of the corporate control and reassembling of life itself?  The basic first step is avoiding genetically modified ingredients as much as possible.  

 

After all, a percentage of every dollar you spend on biotech foods goes towards helping fund future manipulations of nature.

Secondly, it very important to keep well informed.   The public is responsible for educating itself in this day and age. 
Four billions years of evolution have produced these beautiful plants.

Ecosystems are extremely complex.  There are often networks of thousands of different life forms interacting simultaneously.  Genetic engineering, by nature, does not take into account the beauty and necessity of this complexity for our health.

Our ecosystems are being altered in many ways, genetic engineering is just one of them.
