Final answer:
U.S. farms that don't adhere to biological constraints often utilize genetically modified organisms (GMOs) as part of an industrial approach to maximize efficiency, although sustainable and organic farming practices are gaining attention for their ecological benefits.
Step-by-step explanation:
U.S. farms can be run on industrial principles that don’t conform to biological constraints primarily through the reliance on genetically modified organisms (GMOs). GMOs are crops that have had their DNA altered in a laboratory to produce certain desired traits such as increased yield, pest resistance, or drought tolerance.
This use of agricultural biotechnology allows farms to maximize production efficiency with minimal labour and fits within the broader, highly industrialized agricultural systems of more developed countries (MDCs). However, despite increased productivity, it is important to note that other practices like sustainable agriculture and organic farming methods are being advocated for not only their ecological benefits but also because they may improve soil health and reduce reliance on synthetic inputs.
