Put simply, the Earth consists of air, water, ground, and living beings. All of these areas are being hurt by our actions, but one connects them all – the sky. We have inadvertently polluted the air that circulates around the globe and touches all of us to a dangerous — and increasing! — degree. It’s time to fully acknowledge this, decrease the harm of logging, transport, industry, and consumption, and take healing measures for the sky at large and our own suffering lungs.
