Here's a short film that was required viewing when I was in school. If you are of a certain age you may have seen this in school too.

so that explains why they started the genetic modification of crops.

That's right, how to feed the growing population was one of the big problems that science addressed back in the 60's. Food engineering was one of the 20th century's great achievements. Only now people have questions about how we manage our food resources. Factory food may not be something we really want.

When engineers and scientists discovered new ways of doing things they only look short term impact.  The long term impact is not really seen until years later.  It really interesting to see the debates that arise from situations because some people say there is no impact then those who do. 

I have no doubt that the genetic modifications being made to our food will be harmful down the road. The evidence seems to already be appearing.

has anyone noticed that the quality of oranges and orange juice regardless of which brand you buy has pretty much declined over the years since 2004. The juice and oranges taste terrible now. I remember back in 2003 the oranges and pretty much every major brand of orange juice tasted alot better back then and i even contacted the brand known as florida's natural and asked them if they use genetically modified oranges to make their juice and they said no but they could be lying and it appears that oranges at the grocery store seem to rot 10 times faster than they did 13 years ago and it seems to be the same thing with banana's.

I can't say for sure as far as oranges or bananas, but breakfast cereal has definitely gotten worse in taste. Mainly because companies are far more health conscious in their offerings.
