this is talking about the amount of people in areas compared to the amount of space in areas. It is also talking about the structure of farming and usage of land in the past compared to the same of today. The cities are growing larger and using the good/fertile land for housing and human pleasures, which is decreasing the amount of usable land for farming. The more refugees who migrate to the countries and to their cities and the more buildings which are constructed for the living places continue to deplete the amount of land which can be used for farming. The more people, the more need for farming , yet the less amount of good soil to be able to farm. It is also talking about the possible solutions with use of the less fertile land by constructing buildings with the use of solar panels, robotics and computers in which to genetically grow products to continue to feed the ever growing populations, but at the same time using fewer people and more technologies. It stated that the numbers of farmers are less than in the past, so the need for land (fertile land) and farmers are in need and they are trying to find the solution for this ever growing problem.
