Movie Summary
Released: 1973
In the year 2022, overpopulation is out of control and there is not
enough food to feed everyone. The goverment provides a special food
called Soylent Green, which has a secret ingrediant.

Set in the year 2022, Soylent Green depicts a dystopian future in
which the population has grown to forty million in New York City
alone. The water and soil have been poisoned and airborne pollution
has produced a year-round heatwave from the greenhouse effect. Most
housing is dilapidated and overcrowded, and impoverished homeless
people fill the streets.
Food as we know it today–including fruit, vegetables, and meat–is a
rare and expensive commodity. Half of the world's population
survives on processed rations produced by the massive Soylent
Corporation (from soy(bean) + lent(il)), including Soylent Red and
Soylent Yellow, which are advertised as "high-energy vegetable
concentrates". The newest product is Soylent Green - a small green
wafer which is advertised as being produced from "high-energy
plankton". It is much more nutritious and palatable than the red and
yellow varieties, but it is in short supply, which often leads to
riots.
