from what i understand about his research they are controlling for soil quaility.

This is really huge. did everybody read the entire article that nancyLC posted? for a long time we've all thought that nutrient density was going down because we were selecting for yield and shelf life, not nutrition, and because of diminishing soil quality. now there's this other layer, were the increasing c02 levels actually make ALL the plants create more carb matter/less protein and diminishes the vite/mineral content by 8% overall. i think we can all agree that the cause of obesity is multi-factorial and that it doesn't help when people are chugging down gallons of hfcs soda, etc, but if the carb levels in normal plant matter are being affected this much, it's going to be affecting the entire food chain etc. what happens to grass fed cattle when the protein levels in the grass are dropping?

this affects more than just the health of humans... they looked at goldenrod pollen and the affect on bees due to the dropping protein percentages in the goldenrod. http://www.beeculture.com/catch-buz...-bee-nutrition/ we've all heard about colony collapse, and how the honeybees are struggling, and we all know how important they are for pollinating human food crops, etc etc etc. again, it's a multi-factorial problem compounded by mites, migratory beekeeping, etc etc etc, but if the essential proteins necessary for raising healthy bees are missing, you can see that it would be difficult to keep strong bees in the first place.

there is a bunch of his work available on his google site: https://sites.google.com/site/loladze/home it's dense reading, but really interesting.
