Pick up a newspaper or listen to the news and you'll quickly see that our understanding of the Earth and our relationship to it has never mattered more. The Gaia Theory offers insights into climate change, energy, health, agriculture, and other issues of great, if not urgent, importance.
Overall, the Gaia Theory is a compelling new way of understanding life on our planet. It argues that we are far more than just the "Third Rock from the Sun," situated precariously between freezing and burning up. The theory asserts that living organisms and their inorganic surroundings have evolved together as a single living system that greatly affects the chemistry and conditions of Earth’s surface. Some scientists believe that this “Gaian system” self-regulates global temperature, atmospheric content, ocean salinity, and other factors in an “automatic” manner. Earth's living system appears to keep conditions on our planet just right for life to persist! The Gaia Theory has already inspired ideas and practical applications for economic systems, policy, scientific inquiry, and other valuable work. The future holds more of the same.
