Colonialism began with renewable energy. Wind to sail across the world, solar to grow cash crops, and human blood, sweat, and tears to grow them. For the violent and resource-poor tribes of Europe, ‘blood for oil’ began as ‘blood for sun’. Vile companies like the VoC (the first multinational) technically had zero emissions. By this logic, you could say that early colonialism was ‘sustainable’ but it obviously wasn’t. Because the problem isn’t the energy source, it’s what you use that energy for.
Colonialism actively destroyed natural ecosystems to plant cash mono-crops. They brutally hunted land cousins for their skin and ocean cousins for their bodily oils, bringing many species to the brink of extinction, and quite a few over it. To accomplish this all without energy slaves, they trafficked human slaves across the world, leaving millions at the bottom of the ocean. Colonialism both actively and passively spread disease across the world, leading to genocidal levels of depopulation. Then of course there was the outright killing, raping, and stealing. Most perniciously, they framed this all as ‘progress’ and ‘civilization’, which is still the frame we live in. We call this ongoing process ‘capitalism’ or ‘development’ now, but…
