Planetary engineering is the application of technology for the purpose of influencing the global properties of a planet. The goal of this theoretical task is usually to make other worlds habitable for life.
Â Perhaps the best-known type of planetary engineering is terraforming, by which a planet’s surface conditions are altered to be more like those of Earth. Other types of planetary engineering include ecopoiesis, the introduction of ecology to a lifeless environment. Planetary engineering is largely the realm of science fiction at present, although some types of climate change on Earth are recent evidence that humans can cause change on a global scale.
