Technogaianism (a portmanteau word combining "techno" for technology and "Gaia" for the Earth Mother of Greek mythology) is the stance that advanced technology can help restore Earth's environment, and that developing such technology should therefore be an important goal of environmentalists.

This is different from many environmentalists' position and a common perception that all technology necessarily degrades the environment, and that environmental restoration can therefore only occur with reduced reliance on technology.

Technogaians argue that technology gets cleaner and more efficient with time. They would also point to such things as hydrogen fuel cells to demonstrate that developments don't have to come at the environment's expense.

More directly, they argue that such things as nanotechnology and biotechnology can directly reverse environmental degradation. Advanced nanotechnology, for example, could convert garbage in landfills into useful materials and products, while biotechnology could lead to novel microbes that devour hazardous waste.
