- ‘Human activities have dramatically altered the Earth's biosphere and atmosphere during the past few hundred years.’
- ‘The second reason is that it's the mixing place between the biosphere and the atmosphere.’
- ‘So man is now changing the planet, for the better, just as living processes improved the planet, so man by acting on the biosphere improves the planet.’
- ‘Even most of earth is lifeless once you get past the thin film of the biosphere on the surface.’
- ‘Oxygen is one of several vital elements that are constantly consumed and recycled by processes involving the biosphere, the Earth's rocks and volcanoes, and the oceans.’
