Open-ended question: how much fertile land is there per person?

How much fertile land is available per person on the Earth. To help you use the units of land measure, remember that one hectare is 100 square meters. If you were standing in the middle of a hectare, 100m by 100 meters, you would have 50 meters to the nearest point on the sides and 70 meters to the corners.

  • Totally 14.8 billion hectare of land on the surface of the Earth

  2. Given that the loss of fertile land continues, how many hectares of fertile land will be available 2050 when the world population reaches nine billion?
