The single reason we live in a world where scarcity problems are supply chains issues is because of fossil fuels. Stuff does not extract itself, stuff does not move by itself, remove fossil fuels from the equation and the whole civilization you've come to know, love and also hate, crumbles. Current limitations : - Using that almost free energy from the ground changes our environment in a way that threatens our survival (which will have to rely on even more energy expenditure) - What happens when we run out ? (Actually it's more about spending more and more energy for disminishing returns) - Do we have enough to make the transition to renewables/nuclear while shielding ourselves for the currently happening global warming ?
