Message: <blockquote data-quote="Oldvatr" data-source="post: 2206198" data-attributes="member: 196898">The biggest source of atmospheric methane is rotting plants  All hydrocarbons oxidise to either CO2 (aerobic) or Methane (Anaerobic), not just grass. the important thing is that humans cannot eat grass, shrubs or trees.  The earth did a very good job at sequestering carbon in the form of underground hydrocarbons (fossil fuels) which we are using up at a prodigious rate, and it is this activity that is causing the excess GHG.  Burning biomass does not help and growing biomass to burn is not helpful.  Unless we use natural sources for generating our energy either solar or wind or wave or gravity then we are just treading water and not replenishing the carbon store. One source of fuel that is planet friendly is hydrogen, but it is not easy to capture, store, or transport,  But when burnt it only produces heat and water. vapour so is zero carbon emissive, but not zero carbon footprint to generate unless using electrochemical means such as hydrolysis from solar energy.  This is what we should be working on to save the planet.  Note that a useful bi-product of electrolysis is oxygen  So fuel for the car, fuel for me, win, win.  Hydrogen fuel cells are reusable and recyclable, but lithium batteries must be replaced and have a short lifespan.  Wind turbines have a useful life of about 10 years, then they must be scrapped and replaced.  These technoogies have a large carbon footprint and ongoing maintenance expense.  What is the carbon footprint of an electric car nowadays.  I note this subject is never discussed in the press or media.We need to turn the focus away from cow farts and extinction rebellion causing extinction, to solving and supporting relevant technological solutions.  I watch Euronews simply because their Futuris program every day covers these technologies, and is not filled up with games and mobile phone apps.</blockquote>
