What is the primary source of methane emissions?

The primary source of methane emissions is indeed the decomposition of vegetation and digestion in animals. Methane is a natural gas produced through anaerobic processes, which occur in environments where oxygen is limited, such as wetlands, landfills, and the digestive systems of ruminant animals like cows and sheep. During digestion, these animals break down food, producing methane as a byproduct, which is then released into the atmosphere.

This process is significant because methane is a potent greenhouse gas, with a much higher heat-trapping ability than carbon dioxide over a short time frame. The decomposition of organic matter, particularly in wetlands and other anaerobic environments, also contributes significantly to methane emissions. Thus, understanding the biological and ecological processes that generate methane is crucial for developing strategies to mitigate its release and limit its impact on climate change.
