The Earth is definitely not fine and if you think otherwise, you're not paying attention. Yes, the planet will still be here for billions of years but many species, including our own, may not make it much longer at all. Don't cherry pick one data point, air pollution in North America, to make your case. Do some  research on global fisheries, ocean pollution, ground water depletion, desertification, soil erosion, climate, tropical deforestation, species extinction, and on and on. Then tell me if you think "The Earth is fine".
