Since hunger, poverty, and inequality existed before the rise of industrial agriculture in the latter half of the 1900s, it is tempting to argue that global inequality is unrelated to industrial agriculture—that it has separate causes.
Competition between plants in a cropping system and the predation of aphids by lady beetles are examples of interactions at this level in an agroecosystem. The study of the community level of organization is known as community ecology. The most inclusive level of organization of an ecosystem is the ecosystem itself, which includes all of the abiotic factors of the environment in addition to the communities of organisms that occur in a specific area. An intricate web of interactions goes on within the structure of the ecosystem.
High levels of external inputs are needed to level, rip, and cultivate soil, plant seeds or transplant seedlings, apply fertilizers, spray pesticides, irrigate, and harvest crops such as the monoculture broccoli seen in the foreground. on fossil fuels has become so extreme—they are critical for everything from manufacture of nitrogen fertilizer to transport of food from one side of the globe to the other—that food prices have become correlated directly with energy prices. Although agriculture’s dependence on an input that will eventually be used up is a cause for concern, a continued flow of fossil fuels has been guaranteed for the medium term by the development of new extractive technologies such as “fracking” and the exploitation of deeper offshore oil fields.
