Answer:

The predicted growth rate is compared at  -2%

Explanation:

To calculate growth rate, G.R = X(1-\frac{Population}{Carrying capacity of earth})

In the 1960s,

The carrying capacity of the earth = 13 billion

Earth's population = 3 billion

X = \frac{(Growth rate in 1960)}{(1-\frac{Population in 1960}{Carrying Capacity in 1960}) }

X = 0.021 (1-\frac{3,000,000,000}{13,000,000,000} )

X = 0.021 × 0.77

X = 0.01617 = 1.6%

Current population calculation:

Growth Current population (C.p) = 0.016(1-\frac{current population}{current capacity})

Growth Current population (C.p) = 0.016(1 - \frac{6,800,000,000}{3,000,000,000} )

Growth Current population (C.p) = 0.016(-1.267)

Growth rate = -0.020272 = -2%

The predicted growth rate compare to the actual growth rate of about 1.2​% per​ year at -2%.
