C&S = Consequence and Sequel
The invention of the petrol engine made possible automobiles, airplanes, the oil industry and a great deal of pollution.
If all the consequences could have been foreseen at the time, electric or steam engines might have been used in cars.
A new invention, a plan, a rule or a decision all have consequences that go on for a long time.
In thinking about an action, the consequences should always be considered:
Immediate consequences Short-term consequences (1 - 5 years)
Medium - term consequences (5 - 25 year)
