50% Global Methane Emissions Emanate From Aquatic Ecosystems: Study

Almost 50% of the Methane emissions comes from aquatic ecosystems including natural, human-created and human-impacted aquatic ecosystems, claimed a study in journal 'Nature Geoscience'. The paper highlighted that human-made aquatic systems are major contributors as they release 41%-53% of global methane. Reportedly, the coastal aquaculture farms emit 7-430 times more methane than other coastal farms. While global methane emissions remained under control during 2000-2006, it has drastically increased since 2007.
