Read here. As the world population grows, more food will need to be produced on less hospitable agricultural lands and climates. It is well known that environmental fanatics like Paul Erlich, Stephen Schneider, and Obama's science advisor, John Holdren, most likely would not shed a tear for the billions who would starve.....
if food production was unable to keep up. One policy that anti-human scientists push to guarantee genocide of the impoverished is to reduce present atmospheric CO2 levels that now allow vegetation and crops to be super productive. CO2 is absolutely critical to future food supplies, and scientists, like those above, really don't care about the consequences of their CO2 policies on humanity.
How important is CO2 to food production? Here are results from recent peer-reviewed research that the above linked-to article speaks of. Simply summarized, more CO2 is better for food production, and humanity.
"Six scientists from China and Australia tell us in their introduction that “It is considered that the optimal concentration of carbon dioxide (CO2) for plant growth is 800–1000” ppm. We agree wholeheartedly and wonder why so many people refuse to acknowledge the incredible biological benefit plants receive from elevated CO2....the edible shoot weight of leaf lettuce increased by 257% while for stem lettuce, the yield increased by 87%. If you are interested, celery yield increased by 270% and Chinese cabbage increased yield by 227% — all thanks to elevated CO2."...."Like virtually every other plant on the Earth, elevated CO2 will cause cabbage to grow faster and bigger while using less water. Cabbage is particularly vulnerable to a chewing insect, called the diamondback moth, that can spoil all the fun. Recognizing the serious threat of this insect, a team of four scientists from Finland grew several types of cabbage in ambient (360 ppm) and double ambient (720 ppm) atmospheric CO2 concentrations. However, the focus of the Reddy et al. group was not on the cabbage, but on the larvae feeding on the plants. Plants produce a remarkable array of chemicals to protect themselves from the unwanted herbivores, and you guessed it … cabbage in elevated CO2 severely stunted the growth of the larvae."...."They grew tomato plants hydroponically in near ambient CO2 concentrations (near 350 ppm) and in elevated concentrations (near 800 ppm). Wang et al. reported in their abstract “Compared with the control, CO2 enrichment significantly increased the dry matter of both shoot and root, the ratio of root to shoot, total root length, root surface area, root diameter, root volume, and root tip numbers, which are important for forming a strong root system. The elevated CO2 treatment also significantly improved root hair development and elongation, thus enhancing nutrient uptake.” Obviously, elevated CO2 definitely makes tomato plants bigger and stronger."
