That question — what can I do —- is the central question to all of our privilege. How often do I fly? How much do I drive? How much water do I use. How cool should I keep my home? How warn do I keep my home? How much food do I waste? It’s uncomfortable but you and I are in the top 10% richest people in the world. The poor people of the world already don’t water lawns, use AC, throw away food, or fly in airplanes. They have nothing left to sacrifice.
