For best results the Green Revolution relied on expensive fertilizers, chemicals and machinery that were cheaper for the larger farms that bought in bulk. It was often not economical for the smaller ones who had to pay higher costs and interest and receive fewer subsidies. People either had to expand into super farms or get out of the industry in order to remain profitable. Lower profits per unit did not affect larger farms, which had greater turnover and capital. They did not have to be as efficient as smaller farms to survive, and they had more influence over government policy. As fertilizer was increased, the production per ton of fertilizer fell. Increasing amounts of fertilizers were needed to prevent soil nutrient decline. More pesticides were needed to overcome resistance. This degraded the land and damaged the environment so in many cases the long term yields fell after peaking. Apart from China where there was a dramatic fall, the number of hungry people increased during the Green Revolution. It may have been the Chinese revolution and not the Green Revolution that made the difference. Small farms went bankrupt, people moved into the cities, unemployment increased, food distribution became more uneven and poverty increased. Large farms made large profits and often linked with or became multinational companies. (46.2)
