Ocean Acidification, Marine Food Production, and Calcification: Will the first of these phenomena spell the ruin of the latter two, as the air's CO2 content continues to rise?

Subject Index Summary
Nutrient Acquisition: Most species of plants respond to increases in the air's CO2 content by displaying enhanced rates of photosynthesis and biomass production. Oftentimes, the resulting growth stimulation is preferentially expressed belowground, thereby causing significant increases in fine-root numbers and surface area. This phenomenon tends to increase total nutrient uptake under CO2-enriched conditions, which further stimulates plant growth and development.
