52. The Limits to Growth - Donella & Dennis Meadows

 

"If the present growth trends in world population, industrialization, pollution, food production and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years.  The most probable result will be a rather sudden and uncontrollable decline in both population an industrial capacity."  1972

A YouTube explanation I like is by Georg Rockall-Schmidt (parts one, two and three).

51. Red Side Story - Jasper Fforde

 

Great sequel to Shades of Grey

"Oh, brave new world that has such colours in it."
