We claim to live sustainably if we can harvest or extract the earth’s resources without depleting or permanently damaging them. By that standard, no one in a country that devours coal, oil and water — and uses up a quarter of the earth’s resources — can live sustainably. Our collective footprint is just too huge.
To live sustainably, we first need to be part of a greater, systemic transformation toward a culture that regards that as a worthy goal.
