Introduction
Throughout the years, humans have tried to satisfy their unlimited desires with limited resources. The problem of scarcity that arises as a result on Earth is only amplified as the population grows. Historically, there have a number of viewpoints on the sustainability of population growth. Some of them have been more pessimistic than others. One of the most well known pessimistic viewpoints is that of Thomas Malthus.
Thomas Robert Malthus was an English scholar and a professor of history and political economy in Cambridge University. His most famous work was published in 1798, entitled An essay on the principle of population. In this work, he introduced his concept of a Malthusian catastrophe. He theorized that population grows

As the population grows, pressure mounts to produce more food using the same amount of resources. The law of diminishing marginal returns implies that eventually, there is so much more additional output that can be achieved by adding labour with a fixed amount of land and capital. An important assumption for this scenario to be true is a ceteris paribus assumption: that is, all other variable are fixed. If this assumption holds true, Malthus’ theory regarding population would be valid. However, this has never been the case. A variable such as the spread of new and improved capital in the agricultural industry is one that has had a mitigating effect on any relationship between population and subsistence that Malthus had predicted. The Green Revolution was a huge promoter of the mechanization of agricultural production. While it is true that this may have reduced the number of jobs in the agriculture industry, the benefits in the form of increased efficiency is clearly evident. The increased use of technology resulted in the shift of the production possibility of the global agriculture industry, as investments were made in farm capital. This resulted in better production efficiency with using the same amount of …show more content…
Technological and agricultural developments have made it possible to produce more crops on less amount of ground. Not only did the Green Revolution make that possible, but essentially it also prevented the degradation of other land resources. If conventional farming techniques that were in place before had been used to generate that increase in production, millions of hectares of forest and natural grassland would have been used to increase the cropland required to produce that amount of food. The Green Revolution prevented this. As well, worldwide, food production increased 20 percent more quickly than the population, which was essentially the exact opposite of what Malthus had predicted and argued in his book. From 1950 to 1984, growth in the grain harvest easily exceeded that of population, raising the harvest per person from 247 kilograms to 342, a gain of 38 percent. In the 1999 Human Development Report published by the United Nations Development Program (UNDP), it was said that “despite rapid population growth, food production per capita increased by nearly 25% during 1990-1997. The per capita daily supply of calories rose from less than 2,500 to 2,750 and that of protein from 71 grams to 76.” This proves that the famine that was predicted by Malthus, as well as neo-Malthusians, has not come
