Truly hilarious
One thing commentards haven't remarked in this thread: the single biggest factor affecting crop yields is water. Not fertiliser, not GMO/hybridisation, not pesticides, water.
A hydrologist I saw give a presentation some years ago showed that humanity was then already sequestering more than 50% of rainfall for energy and crop use. So-called "carbon pollution" has a profound effect on photosynthetic efficiency. Halving available CO2 doubles the water needs of a crop. Conversely, the increase in CO2 during the 20thC has resulted in ~15% increase in crop yields. Any number of commentards here seem to be both in favour of increased crop yields and vehemently opposed to them.
