- DA sudden decline in the global demand for agricultural labor following the abolition of the transatlantic slave trade
Answer
The intensification of commercial agriculture in industrializing nations to feed growing urban populations
The correct answer is correct because the growth of industrial cities in Great Britain and the United States during the nineteenth century created a massive population shift from rural to urban areas. Because a smaller percentage of the population worked in agriculture while urban food demand skyrocketed, farmers in industrializing countries turned to intensive farming methods. This drove a high demand for high-yield fertilizers like Peruvian guano, leading to a boom in its extraction and export.
