Make Earth Sustainable Again (MESA) is a direct offshoot of the Global Science
Curriculum Project. Global Science was developed over a lifetime (starting in 1970).
Scores of friends, students, professional acquaintances, and fellow educators all had
inputs. No person is an island; hence each of my ideas, no matter how novel, has
been enhanced by comments by friends and associates. To the extent I am aware
of my intellectual debts, I have tried to acknowledge them and give proper credit.
