As the 21st Century opens, humanity has reached a critical junction in our relationship with planet Earth. Rather than humbling ourselves before our cosmic birthright, we are despoiling our home with our indulgent, narcisstic, behavior. Earth is now giving us a loud and clear, first and final, warning. Those who would try to rescue us from ourselves by building a more productive and sustainable global environment have been sidelined. Their only option now is to build a migration plan before it's too late. Mars has become humanity's salvation. The Bryant brothers, Mark and Matt, will take center stage in this drama. They arrive on planet Earth in the 1960s, at the beginning of the human space age. Their Colorado farm is the humble beginning for their stories. One will succumb to a self-inflicted lifetime of pain and suffering, and the other will lead humanity to its next home.
