Atmosphere

Planets often have atmospheres. Atmosphere content and density determine whether the air is breathable by people and animals.

Density is expressed as a percentage value from 0 to 100%. Atmosphere density between 15 and 85 percent can be breathed; below 15% animals cannot draw enough air into their lungs; above 85% animals cannot force the air out of their lungs.

Atmospheric content is classified into categories.

Class	Animals	Plants	Description
Standard	Possible	Possible	Atmosphere is a good mix of breathable gases with few impurities.
Tainted	Possible	Possible	Atmosphere is a tolerable mix of gases to breath. Air may contain visible levels of impurities.
Exotic		Possible	Atmosphere is poisonous to people and animals but may host plant life. Environment suit required.
Corrosive (green)			Atmosphere is poisonous to all plant and animal life. Corrosive to all equipment.
Insidious (purple)			Atmosphere is extremely poisonous to all plant and animal life. Extremely corrosive to all equipment.

Atmosphere density is an environmental commodity used by processes that require an atmosphere.

Processes that use atmosphere density will fetch it from the environment, but the chance of a successful fetch depends on how dense the atmosphere density and percentage of the gas in the atmosphere, which appears in survey reports as the atmosphere density of the world and individual gas percentage.

For example a wind power plant requires just an atmosphere and is therefore only affected by the atmosphere density. But a refinery requires both an atmosphere and the specific gaseous resource which means that it is affected by both the atmosphere density and the percentage of the specific gas.
