Climate change making food crops less nutritious implies research to at least partially countervail it

In the fifties of the past century someone applied some NPK, a fertilizer used in cane sugar plantation, trying to grow manioc. As a result the aerial parts of the manioc grown very fast and strongly. But the roots didn't grow in proportion. As a matter of fact the roots diminished. And the manioc is desired because of some part of its roots. Thus one can say that the NPK diminished the manioc production.

Recent observation on the trees in Amazon found them with the timber less strong. This is so because there is more nutrition on the air, in the form of more carbon dioxide, unbalancing the nutrition mix which they absorb.

Now we learn that the staple cereals growing in an atmosphere of more carbon dioxide presents smaller content of important components to the human being nutrition. As a result, as the carbon dioxide go in its way of growing above the 400 ppm, these components go decreasing, with implications to the human health, demanding agricultural research to offer plants which would bring a compensation, as an adaptation to the global warming.
