Sources and Sinks of Methaneasmussen, 1990). The current annual rate of increase of about 0.8% year. is attributed to increases in industrial and agricultural emissions since some key natural sources (e.g., wetlands and marshes) have been reduced due to development pressure, decreasing their area in various parts of the world
