The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

Consisting of one color or hue (or race). Used by liberal elites like the NY Times to deride communities that are racially homogeneous, whether or not that was by design, coincidence, organic growth, or ethnic clensing. This is a tacit accusation of racism towards those residents. It also puts a halo on New Yorkers who ride on mixed race subways while residing in racial, economic, religious, ethnically pure enclaves fiercely guarded by co-op boards.
