The Economist : How to deal with a falling population
Jul 26th 2007
Malthusian catastrophe : a return to subsistence-level conditions as a result of agricultural (or, in later formulations, economic) production being eventually outstripped by growth in population
net primary production : Primary production is the production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis, with chemosynthesis being much less important. All life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain.
Net primary production is the rate at which new biomass accrues in an ecosystem. Some net primary production will go towards growth and reproduction of primary producers, while some will be consumed by herbivores.
