I interpret the term sustainability to mean the improvement or maintenance of any concept or process. It seems to most recently be related to environmental, social and economic factors in the world. I think te term can be refered to as any particular method or technique that is used to improve and keep up those factors. In the Wikipedia article about sustainability I followed the link for the Brundtland Commission just because I was curious to see what it was. By following the link I found out that the Brundtland Commision was formed by the United Nations in 1983 to address the concern for "the accelerating deterioration of the human environment and natural resources and the consequences of that deterioration for economic and social development." I also followed the link for Rachel Carson(Rachel Carson's) because she seemed to be important to the history of environmental sustainability. I learned that she was a marine biologist and nature writer in the 1950s who helped advance the environmental movement with her writings. As I continued through the article I saw something about a sustainable food system. When I followed that link(Sustainable food system) I read that accoriding to the American Public Health Association, the system is "one that provides healthy food to meet current food needs while maintaining healthy ecosystems that can also provide food for generations to come with minimal negative impact to the environment. A sustainable food system also encourages local production and distribution infrastructures and makes nutritious food available, accessible, and affordable to all. Further, it is humane and just, protecting farmers and other workers, consumers, and communities." In that same section I saw a link for monounsaturated fat, which I have never heard of before. I followed the link and read that monounsaturated fats are fatty acids that have a single double bond in the fatty acid chain and all the carbon atoms in the chain are single-bonded. I didn't really know what they meant by a double bond so I decided to check that link out and it took me to a page about covalent bonds.I then learned that a covalent bond is characterized by the "attraction-to-repulsion stability that forms between atoms when they share electrons."

In the article about Rachel Carson I would have changed some of the wording that the writer used. I would have changed: 

"Carson started her career as a biologist in the U.S. Bureau of Fisheries, and became a full-time nature writer in the 1950s. Her widely praised 1951 bestseller The Sea Around Us won her financial security and recognition as a gifted writer. Her next book, The Edge of the Sea, and the republished version of her first book, Under the Sea-Wind, were also bestsellers. Together, her sea trilogy explores the whole of ocean life, from the shores to the surface to the deep sea." 

to say: "Rachel Carson began her career as a marine biologist in the U.S Bureau of Fisheries. She later became a full-time nature writer in the 1950s. Carson won her financial security and recognition as a gifted writer thanks to her 1951 bestseller The Sea Around Us. Her next book, The Edge of the Sea, and the republished version of her first book, Under the Sea-Wind, were also bestsellers. Together, her sea trilogy explores ocean life as a whole, including the shores, the surface, and the deep sea."
