What does it mean to be a goodhuman? I assume it means good
person and that can be a very complicated thing sometimes.

Good how? Socially, personally, environmentally, spiritually?

Some of the goodest (best) people I know can be shockingly
not-so-good sometimes. 

We are a rapidly growing species on this planet and we've got
to live together and keep our environment clean. Being
GoodHumans helps us achieve this.

Being good to me means being a friend to others no matter who
or what they are. Littering is as horrible to me as violence.
We all have differing views on what it means to be a
goodhuman and we are not always going to be as consistent
as we'd like. The important thing is that we TRY to be 
GoodHumans.
