What is green chemistry? According to McGraw-Hill (2003), green chemistry is “the use of chemical products and processes that reduce or eliminate substances hazardous to human health or the environment.” On a simpler note, this new approach to botanic life is making a large impact on nature and the environment. The improvements made by researchers studying green chemistry have been beneficial to the ecosystem because they are helping rid the atmosphere of any substances or chemicals at risk of damaging the health of the environment or its people. Nowadays, the number or companies who have adopted the idea of green chemistry is increasing rapidly. This is most likely due to the fact that it has many advantages in human health. In addition to health, green chemistry is also financially beneficial to companies. Finally, green chemistry is a good way to comply with the environmental laws and standards that have been set (Credo Reference, 2005.) Although there are many ways to support green chemistry, the most common route is the use of greenhouses. “Greenhouses are structures used to grow plants under protected conditions” (Albright, 2004). This topic was chosen to inform readers about the history, purpose, advantages, disadvantages, heat management, and future improvements of greenhouses. However, it was mainly selected to advise individuals about the technology that greenhouses involve and require. Presently, Greenhouse technology is one of the most widely researched topics in the field of green chemistry. Although plenty of advancements have been made in the mechanics and technology of a greenhouse, the first identified greenhouses had little or no technology at all. The history of greenhouses begins with the Romans, who used greenhouses to protect their crops from harmful weather (Barnes, 2008). The Romans believed that in order for their plants to thrive in a greenhouse, their ability to receive heat was much more important than their ability to receive light (Barnes, 2008). In 1599, a French botanist named Jules Charles created the first practical greenhouse, or glasshouse, their former name. Its purpose was to serve as an orangery and help orange trees grow and thrive in destructive weather. These innovative structures soon became extremely popular around Europe (The History of Greenhouses). During this time, the structure of greenhouses was improper. However, the builders made altercations by substituting a flat roof with a curved roof, which allowed the sun’s rays to hit at greater concentrations. They also discovered that building the structure with iron helps absorb more light than wood when the house is built with wood (Barnes, 2008). Eventually, after they had been built throughout European territory, the idea of greenhouses came to America. In 1737, Andrew Faneuil built the first recorded American greenhouse. By the mid 1800’s, greenhouses had become popular throughout the nation. While many of the greenhouses were heated with air warmed by furnaces, some greenhouses were built into the ground and were heated by large windows. This strategy is still fairly common (The History of Greenhouses). All of the progress and improvements that have been made on greenhouses are not only beneficial to the study of greenhouse technology, but they also help enhance the purposes of a greenhouse. Greenhouse structures are extremely helpful and accommodating in many ways. They are used by many planters and botanists to create a controlled environment for their plants. Being able to control one’s plants serves as just one of a greenhouse’s many purposes. According to Albright, “environment control typically encompasses air temperature, supplemental light, air movement (circulation and mixing), and carbon dioxide concentration” (2004). Many advanced greenhouses use computers and high-end technology to manage the environment needed for sufficient plant growth. These systems “allow stable control of the plant environment,...
