We have all heard of the term of selective breeding, which consists of picking two specimens with traits you find useful and breeding them to produce offspring with the desired trait. This is a practice that has been used since antiquity—ranging from breeding the more docile wolves of the pack which eventually led to modern age dogs, to the Dutch simply selectively breeding carrots in order to make them reach a bright orange color.¹ While this practice has always been used, it wasn’t until the 20^th century that it reached a world status by giving humanity a more reliable source of food, and consequently saving over 200 million lives.²

Norman Borlaug was an American plant pathologist who obtained his bachelors, master’s and doctorate degrees from the University of Minnesota in 1937, 1939, and 1942 respectively. In 1944, Norman was appointed by the Mexican government and the Rockefeller Foundation to lead a research project focused in scientific research in genetics involving plant breeding with a purpose of improving yield in crops. He was stationed in northern Mexico and immediately began experimenting with selective breeding there.³

The 1940s were a rough stage in human history; while the population was growing at an accelerated rate in undeveloped countries such as India, Pakistan, and Mexico, crop yields were growing at a much slower rate in the same countries. International aid consisted of “first world” countries sending surplus food to “third world” or “developing” nations. This proved effective for some time, but the nations sending out the aid quickly realized that they were only temporarily fixing the problem.⁴ A solution for this critical problem would eventually be provided by the research Norman and his fellows did in Mexico, following the development of a dwarf plant.

When Norman arrived in Mexico in 1944, he arrived in a country where not enough wheat being was produced to feed the general population, inciting concern on how the country would feed its people in the future.² Mexico relied on importing the remainder of the wheat needed to feed its people, and it yearned to rise to self-sufferance. Norman worked with already existing varieties of crops, selectively breeding them to be more resistant to weather and plagues. Norman himself claimed that “It is the unusual breadth of adaptation, combined with high genetic yield potential, short straw, a strong responsiveness and high efficiency in the use of heavy doses of fertilizers, and a broad spectrum of disease resistance that had made the Mexican dwarf varieties the powerful catalyst that they have become in launching the Green Revolution.”⁵

The effect that this High Yielding Crop had in Mexico’s food production was immense. In the span of six years, Mexico’s wheat production tripled, accomplishing something quite impressive in such a short amount of time. This drew the attention of other developing countries, namely India and Pakistan, who requested help in getting their crop yield to rise by utilizing Norman’s High Yielding Crop as they were also struggling to feed their people.⁶

Agriculture in India at the time was known for being very primitive and based on low yields. The only reason they had managed to support the population growth was due to the large amounts of land dedicated to agriculture.⁷ In India, about 70% of the population was involved in some form of agriculture, while the United States boasted only 5% of its workforce in the same economic sector. This alone should provide an example of just how efficient agriculture was in the US compared to developing nations.⁸

The hybrid crops were introduced to India and Pakistan in 1967, and they were generally accepted by the populace at large. In a matter of years, its utilization started giving positive results. India and Pakistan would become self-sufficient in wheat and cereal production by 1974, proving once again the advantage of the high yielding crops.⁹

The success in India and Mexico drew the attention of the Nobel prize awarding committee, who, after a careful review, decided to give Norman the prize in 1970. Norman’s high yielding crops had lowered child mortality and raised life expectancy throughout the world, saving millions of lives. Each Nobel Laureate receives a monetary prize to ensure their economic stability throughout their lives, but Norman only used the money he received from the Nobel prize to establish a food world prize, one to honor contributions in improving the world’s food supply.¹⁰

Soon after India, many other countries started using Norman’s techniques to try to become self-sufficient in food production. Norman trained a group of scientists that would eventually spread the “green revolution” to the Middle East, Northern Africa, and South America.¹¹ While the High Yielding Crops were very successful around the world, the progress in Africa was wholly stagnant. This phenomenon was due in part to Africa’s low level of development compared to the other nations where the crops were implemented. Transportation methods in Africa were not as developed as they were in India, and the crops and fertilizers could not easily reach every farmer.¹²

Norman knew this could be a problem, and, in 1986, started working towards improving African agricultural development.¹³ Norman’s hard work, coupled with funding from Jimmy Carter and Roichi Sasakaw, a Japanese industrialist, resulted in the doubling of yields in many African countries.¹⁴

The fight against mass starvation hadn’t been won yet. Norman’s crops, while being helpful, also had a huge weakness: the interbreeding of all the wheat specimens to produce the high yielding variety had resulted in lower diversity of wheat as a species. This meant that a single plague could result in the catastrophic event of the high yielding variety becoming extinct. Because Norman’s plants were being used worldwide, a virus could leave humanity with little to no food supplies. Norman’s crops were also heavily dependent on fertilizer, which resulted in constant damage to the surrounding environments. Without fertilizer, the crops would be even less efficient than the regular non-high yield variety.¹⁵

Norman worked the remainder of his life to improve crop yields and raise awareness about world hunger. His work fell victim to many critics, and they often claimed that he favored monoculture, which describes the idea of mass planting and harvesting of a single crop, which produces a detrimental impact on the environment, turning agriculture a corporate business.¹⁶

Regardless of the critics, Norman is nevertheless credited for saving millions of lives and improving the quality of life in most undeveloped countries. He left a legacy of service and became an icon for the scientific community. Several companies have continued his work by researching higher yield crops to prevent malnutrition. Norman died with a sense of accomplishment in 2009 at age 95 in Dallas, Texas.¹⁷

When wheat is ripening properly, when the wind is blowing across the field, you can hear the beards of the wheat rubbing together. They sound like the pine needles in a forest. It is a sweet, whispering music that once you hear, you never forget.
