Degrowth must work. GDP is related to fossil fuels, and we are passing the global peaks. Fossil fuels will go down, and therefore the GDP will follow.<p>We don't have a choice, we don't have serious replacements to fossil energy. Energy <i>will</i> go down, and therefore we have to prepare for that. Either we will degrow by force (without having prepared anything, it will mean a lot of poverty and instability), or by choice (which hopefully will look more like sobriety than poverty).<p>The sooner we accept that, the better.
