Interesting film. No hard specifics. This year relative to GDP, China dumps 6 times more carbon into the air than the USA and India only dumps double ours. The USA contributes very little plastics to our oceans while about 90% comes from the orient. If, in fact we have had 6 or 7 ice ages and that the last one was about 10000 years ago, then why would not the planet continue to warm until the cycle reverses and again we descend into another ice age? yes, we should strive for sustainable living, but controlling other countries carbon emissions that will be difficult, especially if they manipulate any data. Using rocket stove for home heat, if one is actually using renewables for fuel and after the free power of the sun is maximized. However, as the sun produces about 1000 btu for every square yard per hour, too often we miss the opportunity to build a south facing greenhouse for day time isolation, with night time insulation. Alas, we have not asked our designers to lay out subdivisions with solar maximization (for northern USA) and minimal insulation for those in warmer climes. Accounting for the sun in building has been around since the Anasazi, but, we seem to have a problem incorporating their design elements into our homes. Jim Johnson 10 2020
