Jul 15 Word of the Day
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.
Billionaires are having a dick swinging space race while the earth experiences record breaking heatwaves that cause sea creatures to literally cook inside their shells. We need planetary quarantine.

A amazing friend, she'll always be there for you and cares about you whether you know it or not. People sometimes think she's loud or annoying, but that's only when she's in front of other people, and feeling insecure, if you really knew her, you'd know how fun she can be. She's very family orientated. She generally doesn't care what people think about her, so sometimes she can be portrayed as a bitch, but really isn't everyone a little bitchy sometimes?
'Oh my gosh sinead's so loud..'
'no, you don't know her man, she's actually really cool.'

a girl who lives on a Ranch in the sandpit. Has a lot of friends who adore her. Spends most of her time at the Irish Village. A superstitious girl who doesn't like birthdays to fall on odd days of the year. A loyalty member of the brunch association and Fibbers Bar. On occasion likes to dress up and play an old hag. Has hit Rock Bottom more than most.

A girl who deserves every happiness in the world.
