Plastic is a word that originally meant “pliable and easily shaped.” It only recently became a name for a category of materials called polymers. The word polymer means “of many parts,” and polymers are made of long chains of molecules. Polymers abound in nature. Cellulose, the material that makes up the cell walls of plants, is a very common natural polymer.
Over the last century and a half humans have learned how to make synthetic polymers, sometimes using natural substances like cellulose, but more often using the plentiful carbon atoms provided by petroleum and other fossil fuels. Synthetic polymers are made up of long chains of atoms, arranged in repeating units, often much longer than those found in nature. It is the length of these chains, and the patterns in which they are arrayed, that make polymers strong, lightweight, and flexible. In other words, it’s what makes them so plastic.
These properties make synthetic polymers exceptionally useful, and since we learned how to create and manipulate them, polymers have become an essential part of our lives. Especially over the last 50 years plastics have saturated our world and changed the way that we live.
The First Synthetic Plastic
The first synthetic polymer was invented in 1869 by John Wesley Hyatt, who was inspired by a New York firm’s offer of $10,000 for anyone who could provide a substitute for ivory. The growing popularity of billiards had put a strain on the supply of natural ivory, obtained through the slaughter of wild elephants. By treating cellulose, derived from cotton fiber, with camphor, Hyatt discovered a plastic that could be crafted into a variety of shapes and made to imitate natural substances like tortoiseshell, horn, linen, and ivory.
This discovery was revolutionary. For the first time human manufacturing was not constrained by the limits of nature. Nature only supplied so much wood, metal, stone, bone, tusk, and horn. But now humans could create new materials. This development helped not only people but also the environment. Advertisements praised celluloid as the savior of the elephant and the tortoise. Plastics could protect the natural world from the destructive forces of human need.
The creation of new materials also helped free people from the social and economic constraints imposed by the scarcity of natural resources. Inexpensive celluloid made material wealth more widespread and obtainable.
Answer:
The answer should be D. Sorry if incorrect. Hope this helps.
The cities with the largest populations in the Northeast are: New York City, Philadelphia, Hempstead, Washington, Boston, Baltimore...
Explanation:
The Northeast is the region in the United States that has the biggest population density. This region was one of the first that was inhabited by the European colonists, and it was the first one to industrialize. This resulted in lot of people settling in over time, and the cities were constantly growing, and they still do. It is an enormous megalopolis in fact, comprised of numerous cities and towns stretched in linear manner along the Atlantic coast.
- The largest cities in this region are New York City, Philadelphia, Hempstead, Washington, Boston, and Baltimore.
- The mentioned cities are the ones that individually have a population greater than half a million people.
- New York City is the largest of them with more than 8 million people, while Baltimore has just slightly more than 600,000 people.
- This part of the United States is considered to be as one of the richest, economically most developed, and being the center of the country in numerous things.
