My Country Is Called Earth
by Lawrence John Brown
A man worried about the world he would be leaving to his children falls asleep in 1992 and wakes up in 2076. Fearing the worst, he asks the people he meets how the major problems of 1992 were resolved. Two weeks later, he returns to his time with the answers. This book, first published in 1994 but still relevant today, is not an apocalyptic nightmare, but a look at a possible healthy future earth.
