No mercy monday is when you and a group of friends are horrible to each other, call each other out, and be brutally honest all day and no matter how mad someone gets you don't stop that's were the "no mercy" comes in. Me and my friends love this. It should help you and your friends be nicer to each other through out the week. But come Tuesday, you cannot be mad at someone for what they have said because that's the whole reason of no mercy monday, to release tention and get it all of your chest.It's kind of a friendship building exercise for horrible people. ~Warning: you have to be good friends to participate in this~

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.
