Type 0

A Type 0 or K0 civilization extracts its energy, information, raw-materials from crude organic-based sources (i.e. food/wood/fossil fuel); pressures via natural disaster, selection, and societal collapse creates extreme (99.9%) risk of extinction; it is capable of orbital spaceflight; in fiction, societies that fail to improve social conditions, environmental and medical understanding concurrently with other advancements, frequently accelerated their own extinction. It could be considered similar to 21st-century Earth.
