What is one environmental benefit of anaerobic digestion?

Anaerobic digestion is a biological process where microorganisms break down organic matter in the absence of oxygen. One of the significant environmental benefits of this process is that it reduces methane emissions associated with organic waste decomposition. Typically, when organic waste is left to decompose in landfills or other aerobic conditions, it can produce methane, a potent greenhouse gas that contributes to climate change. By using anaerobic digestion, the organic waste is instead converted into biogas, which mainly consists of methane and can be captured and used as a renewable energy source. This not only helps in mitigating the amount of greenhouse gas released into the atmosphere but also provides a sustainable energy solution, showcasing a dual benefit of waste management and energy production.

The other options, while they may relate to aspects of environmental management or agriculture, do not accurately represent the primary environmental benefit of anaerobic digestion in counteracting methane emissions.
