The backstory of the Dred Scott v. Sanford, was essentially that Dred Scott, a slave of Sanford, sued for his freedom, since his master moved to a free territory, he should be automatically freed, per the requirements of the land. However, the Supreme Court ruled that he still had to stay as a slave, as he was Sanford's property, and property is not limited simply because of the type of territory they were in. Essentially, as long as the slave was bought at a slave state, the owner can keep him/her regardless if they move to a free state or not.
The effect of this on the North was public outrage, as they believed that the south would overstep and become too powerful as compared to the North. After all, the ability to move slaves into newly 'created' western territories, coupled with the historical 3/5th Compromise, resulted in large significant portion which may become slave territory, thereby tipping the balance of governmental power in favor of the south. The second effect of the Dred Scott case was the doubling down of the efforts towards the Underground Railroad, as well as the extension to British Canada, which was a free state. In essence, it was not enough for slaves to escape to a northern territory, as they can still be caught and returned to their masters under the Dred Scott v. Sanford ruling. However, if they were to escape to Canada, the US would then have no authority or obligation in which to capture the escapee.
Essentially, the North protested the case ruling, and put in more effort in ensuring that escaping slaves would stay free, by extending the underground railroad into Canada.

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.
Main Answer:The airy settlement that we explored had been built by the Anasazi, a civilization that arose as early as 1500 B.C. Their descendants are today's Pueblo Indians, such as the Hopi and the Zuni, who live in 20 communities along the Rio Grande, in New Mexico, and in northern Arizona.
Side Answers:
Which tribes of today are the descendants of the Anasazi?
The descendants of the Anasazi are still around today, though. The Pueblo and the Hopi are two Indian tribes that are thought to be descendants of the Anasazi. The term Pueblo refers to a group of Native Americans who descended from cliff-dwelling people long ago.
Who were the Anasazi and where did they live?
The Anasazi lived in the four-corners region of North America. They had three major centralized populations in three different places: Chaco Canyon (New Mexico), Mesa Verde (Colorado), and Kayenta (Arizona). They were in this region from c. 490 AD to the 1300s AD.
Where was the Anasazi tribe located?
The heart of the Anasazi region lay across the southern Colorado Plateau and the upper Rio Grande drainage. It spanned northeastern Arizona, northwestern New Mexico, southeastern Utah and southwestern Colorado—a land of forested mountain ranges, stream-dissected mesas, arid grasslands and occasional river bottoms.
