on May 27, 1907 in Springdale, Pennsylvania. She graduated magna cum laude (with honors) from Pennsylvania College for Women in 1929. Carson was also involved at the University of Maryland when teaching zoology and spent her summers at the Marine Biological Laboratories in Woods Hole, Massachusetts. Carson then completed her master’s degree at John Hopkins in zoology in 1932 of June. Upon graduating, Carson began working at the U.S. Bureau of Fisheries to write radio scripts. She eventually became

“Given time― time not in years but in millenia― life adjusts, and a balance has been reached. For time is the essential ingredient; but in the modern world there is no time. The rapidity of change and the speed with which new situations are created follow the impetuous and heedless pace of man rather than the deliberate pace of nature.” ― Silent Spring by Rachel Carson (1962) During the heightened economic and technological growth that comes with every war the world fell in love with the very

surprising, others not as much due to reoccurring themes in the economy. To understand pesticides, we must look at the facts about them. According to the EPA, pesticides are chemicals specifically designed and sold to prevent, destroy, or repel pests from garden, greenhouses, fields, and orchards (Learn About Chemicals Around Your House). Charlotte Gerber’s article, How Do Pesticides Kill Bugs, explained that pesticides targets insects and kills them by attacking the nervous system and then when

This method can however be extremely efficient as humans are able to exert their control over the plant in order to produce what is demanded. On the other hand, polyculture is a form of hedging as many types of plants and their strains are grown in a singular area and while some may succumb to disease or pests, others will thrive. Contrasting the two forms of plant growth is the best way to see the advantages and disadvantages of monoculture.

Biotic factors: predators, parasites, soil microorganisms, pests and diseases. (c) Edaphic factors: soil pH, soil texture and soil structure. 3. Rock formation (a) rock types: igneous, sedimentary and metamorphic; (b) rock formation processes. Formation, composition and properties of soil (a) Factors of soil formation: parent rock, topography, organisms, climate, vegetation and time (b) Processes of soil formation: physical, chemical and biological processes.

Biofuels: A clean alternative to fossil fuels? Biofuels, like fossil fuels are hydrocarbons made from a living or once lived organism that humans can use to power something and uses biological carbon fixation, a process that takes inorganic carbon and converts it into organic compounds (Wikipedia). However, unlike fossil fuels, which can take millions of years to form, biofuels are produced in a short period of time such as days, weeks, or months. Because humans have been burning fossil fuels

method puts ecologically friendly techniques into practice by relying on biological pest management and compositing (Dimitri). Organic food is grown without using synthetic chemicals, antibiotics, or hormones in both crop production and raising livestock (Dimitri). According to the International Federation on Organic Agriculture Movements, the purpose behind organic food production is to “encourage and enhance the biological cycle within the farming system to maintain and increase long-term fertility

reasons that using pesticides is a good idea for controlling the ash borer. ultimately you will decide for yourself what is most important. However, in my personal opinion, in order to protect the ash trees in our area, we need to use pesticides to control the emerald ash borer and the pesticides as well as the way they are applied do not pose any threat to humans whatsoever. Most people know of the existence of pesticides but many of them also do not have to use them nor do they know

Throughout her book are numerous case studies documenting the harmful effects that chemical pesticides have had on the environment. Along with these facts, she explains how in many instances the pesticides have done more harm than good in eradicating the pests they were designed to destroy. In addition to her reports on pesticide use, Miss Carson points out that many of the long-term effects that
