John Davis and Ray Goldberg wrote the book A Concept of Agribusiness in 1957 through the Harvard Business School. In 1952, Harvard Business school launched their own program studying the connection between agriculture and business. The research conducted by Davis and Goldberg is the first product of research from this school of study. 

The term agribusiness was created to refer to the many processes that surround the economics of farming. The processes include the actual farming of the crop, to later sales, marketing and distribution. 

The only option that involves agriculture is the company that produces the fruit juices.

The study of agribusiness is referred to as agribusiness management. This name comes from the combination of agricultural economics and and management studies. 

Natural selection is the process by which organisms that survive best pass on their genes, ensuring genetic modification over time. This is always occurring in the natural world. This can be contrasted with artificial selection, which occurs when humans select for certain traits. Bioballistics and biolistics are two terms for the same idea. They refer to the process of using a "gene gun" in order to introduce genetic material into an organism. 

Thus, natural selection is the only option which doesn't involve human intervention.

The acronym GMO stands for “Genetically Modified Organism.” It is used in common parlance to refer to a crop whose genetic structure has been altered to make it more useful and efficient for human purposes. GMOs are often controversial because some scientists claim that their health effects have not yet been realized.

The term “biotechnology” is applied to any technological innovation that is designed to improve the usefulness of plant and animals species for human agricultural purposes. Biotechnology is what drove the population growth of the Green Revolution. It is often controversial, such as in genetically modified organisms.

Genetically Modified Organisms are crops whose genetic makeup has been altered to encourage some positive traits and eliminate some negative traits. These crops, however, are not universally supported. Opponents of GMOs argue that the environmental consequences remain unknown and could be potentially devastating. Even opponents of GMOs recognize their potential to benefit those in areas of economic and food scarcity.

The United States and Brazil together account for almost ninety percent of the world’s production of ethanol fuel and are by far the biggest uses of ethanol to fuel motor vehicles. Brazil’s government has made it an official policy and ethanol usage continues to rise in Brazil.

Genetically-modified organisms are a controversial topic in contemporary agricultural geography. GMO's are crops whose genetic makeup has been altered to encourage positive traits and eliminate negative traits. This leads to a more efficient process and a more reliable product, but has many potential downsides.
