Question

Assume that the maximum arable land area on Earth is 4.00 billion hectares. Using the smooth curve that you created above, determine the year in which the human population is likely to run out of arable land for agriculture?

Answer 1

Answer:

2048 is when the arable land is likely to run out for the human population.

Explanation:

Using standard observation techniques, one can observe that when the curve cuts the y axis at 4.00 billion hectares, the curve cuts the x axis at a few spaces before the line labelling 2050. Using a method of linear extrapolation, we can measure the distance of these spaces and deduce that the difference corresponds to 2 years. This number of 2 years when subtracted from 2050 results in the year 2048 at which arable land is expected to run out.
