I am definitely of the same opinion regards the overzealous policies being
developed to control carbon emissions, and that man-made "climate change" is
simply a hoax, but a quick internet search with the terms "wheat, carbon
dioxide, and cyanide" will quickly turn up some research studies on this
threads topic. The one paper I glanced through had some interesting
discussions between botanists that certainly have more knowledge regarding
the subject than I.

Regardless that CO2 emissions are being inappropriately used as a lever for
social policy change we need to keep atuned to real environmental dangers
based on good science.
