To assert that the sinful act in terms of unsustainability, for example, is merely extracting and using oil, which releases greenhouse gases and warms the planet, is a grave underestimation of the issue. The far more egregious act is that for all the various intents and purposes that energy could have been used for — such as fuelling innovation, which could have generated something of more value than the sum of its parts — it is instead used to build tanks and weapons with the intention to destroy lives, homes, and cities.
