I have to admit that I don't get it.:confused3: At no time in history has average life expectancy been better than today.
A simple graph such as this one supports this completely. If you want to look at more current data and projections for the future,
try this link (it's long). If you want to use methods of the past and/or eat only organically grown food, good for you.
Nobody will stop you if you can afford it.
I understand arguments about business ethics and questionable practices by chemical companies. I think those arguments are separate from arguments that say our food is dangerous. History just doesn't show this to be true.
