Once upon a time there was global trade in whale oil. It was used for lighting, cooking, heating and people were so sure it would never run out because the ocean was so big. Then several species were hunted to extinction and many other species became endangered and trade in whale oil had to stop. Petroleum is a finite resource. Corporate controlled governments are fighting wars over oil right now because it’s almost gone. Between 5 and 8 years of oil left. America has spent a century destroying public transportation and enslaving the population to the automotive and fossil fuel industries. They can’t switch to renewable energy fast enough. Without fossil fuel for their cars Americans will be finished.
