Answer:
The flaw in Ehrlich's argument is imprecision.
Step-by-step explanation:
Known worldwide for alarmist book "The Population Bomb" (1968), Paul Ehrlich stated that by 1970:
"... hundreds of millions of people will starve to death in spite of any crash programs embarked upon now..."
The main idea of his book - jointly written with his wife Anne Ehrlich, is to aware humanity about the rapid growth of the earth's population. In fact, since the 18th century, it has grown 600% but even if our planet's resources are finite the catastrophic end the Ehrlichs predestined is unlikely to happen in the upcoming years.
