to change the binomial nomenclature of human beings from "homo sapiens" to "homo ludens"
WHY?
Human beings are not wise. Wisdom is a subjective definition. Other animals play but only humans focus as hard or as intrinsically upon the concept. Maybe some humans can display 'wisdom' every other day or so. But every human being can demonstrate a desire and appreciation for play from the age of 3 - where they differentiate themselves from apes and orangutans - onward without any stops. We PLAY. We always play.
Another consideration. What if whales or dolphins are 'sapient', that is self-aware tool workers (which we have evidence they are), we can call them "platanista ludens" and avoid the discrimination of aliens when they notice how badly we treat our brothers in self awareness.
The movement is growing.
that sounds more trouble than it's worth
