“The Green Morning” first appeared in The Martian Chronicles.

The next several chapters describe the transformation of Mars into another Earth. Small towns similar to those on Earth begin to grow.

In “The Green Morning”, one man, Benjamin Driscoll, makes it his mission to plant thousands of trees on the red plains so oxygen levels will increase. Due to some property of the Martian soil, the trees he plants grow into a mighty forest in a single night.

A 1997 edition of the book advances all the dates by 31 years. This story advances from 2001 to 2032.
