Conteúdo:  In its attempt to grapple with the increase in the market demand for food, mainly after the second war, agricultural activity has broken into the cycle of renewal, failing to return to the life-support system that has been removed from it in the trade-off process. The high-yields achieved by the intensive monocropping system, which was launched during the green revolution, have been based on high-external inputs, such as genotypically similar varieties, crop-protection chemicals, and energy consuming equipments. The loss of carrying-capacity and resiliense of agroecosystems, for instance, are strictly related to the deleterious impacts of high-intensive inputs on the biodiversity of microorganisms and invertebrates of arable land. Therefore, if they are to be overcome, they require explicit recognition and analysis. The assessment of impacts caused by modern agriculture is particularly vital to formulate alternatives as a means of increasing per capta productivity while decreasing risks of degrading of the life-support system.
