Earth & Environment

The "third rock from the Sun"—Earth. With an orbit neither too close nor too far from the Sun, it occupies a unique position in the Solar System. It's the only planet known to man with the right conditions for the origin and evolution of life. During Earth's 4.5 billion-year history, a combination of processes has transformed it into a watery blue, living planet. The Earth's ecosystems involve complex interactions between the biological (living) and physical (non-living) worlds. Scientific research helps us comprehend our effects on the environment and how the environment in turn responds to impacts of our activities.
