Recycling is a key to energy reduction. Therefore, ECO-XMPP® clients SHOULD actively discourage users from generating new messages. ECO-XMPP® servers MAY keep a history of interesting messages that they can substitute for the mindless drivel generated by the typical IM user (cf. Instant Messaging Intelligence Quotient (IM IQ) ), or even refuse to deliver such messages to the intended recipient.
This specification is designed to meet the following requirements:
- Save the planet.
- Love your mother. 
- Reduce, reuse, recycle.
- Earth first, humans second, and computers a very distant third.
For the Earth: live in the dark, the cold, be hungry, be lonely, and most importantly be afraid then die horribly.
If you love the Earth choose ritual suicide!
