The most recent world population doubling has occurred in about 40 years. Suppose that
the next doubling also occurs in 40 years, but that agricultural progress also manages to
double food production. Then how many people will be starving 40 years from now, as
compared to the numbers starving now (which are about 850 million). What do you think?

In the next ~40 years the earth's population is predicted to be 9.6 billion, up from the current 7.2 billion, so you are wrong right out of the gate. And that's the new *higher* estimates.

UNITED NATIONS -- Earth's human population is expected to coast upward to 9.6 billion by 2050 and 10.9 billion by 2100, up from 7.2 billion people alive today, a United Nations agency has projected.
