Agricultural engineering can help increase food production to address issues like overproduction, underproduction, and rural job losses. It allows farms to be harvested more quickly through machinery. However, it also contributes to environmental issues like releasing greenhouse gases and damaging natural ecosystems. "Green" agricultural engineering using biofuels could reduce emissions and provide more sustainable options. While increasing farm size and production, it may also decrease the number of people needed to work on farms and affect rural societies. Overall, agricultural engineering presents both opportunities and challenges for food supply, the environment, and rural communities.
