• Resumen

  • Tyrell talks about James Lovelock's Gaia theory. Life has steered Earth's environment over billions of years, helping to keep it stable and comfortable for living things. That's the crux of Lovelock's Gaia hypothesis. He made powerful arguments in favor of the Earth as a self-regulating system. He proposes three main arguments for Gaia: that Earth is an extremely favorable habitat for life; that life has greatly altered the planetary environment, including the chemical composition of the atmosphere and the sea; and that Earth's environment has remained fairly stable over geological time.
