You put together quite a long string of different thoughts there.  It is nowhere near as simple a clear connection between approved pesticide exposures and cancer.  In fact, one school of thought that seems to have merit is that we are seeing more cancers at more advanced ages is simply because we have more people living longer than ever before.  Cancer has been with us longer than we've been making pesticides.  Perhaps more of us are living long enough now to be killed by it.

Prepared food chemicals are a different issue altogether, and we do eat too many of them....that is why more and more people are pushing back on processed foods.

And it isn't about cost that we can't feed everyone with organic foods.  Our growing space is limited and we need more yield, not less, if we wish to feed everyone properly.
