Over a period of 1000 years the Native Americans transformed Maize by using selective breeding. Maize was a staple crop and food in their diets. The American Indians would also ground dry corn kernels into corn meal which would be used for cornbread, corn syrup, or corn pudding. The husks of the corn cob were braided into masks, baskets, and dolls. Christopher Columbus first discovered corn in 1492 in Cuba.
In 1793 Eli Whitney of Massachusetts invented the cotton gin. The cotton gin is a device that can remove cotton seeds from cotton easily. The process uses a small screen and pulling hooks to force the cotton through the screen. One worker using the cotton gin can clean cotton as fast as 50 workers hand picking it. Q. That’s a wonderful invention!
"A Brief History of Sugar." A Brief History. 11 Oct 2008 <http://www.irish- sugar.ie/noframes/nf-pages/nf-hist/nf-hist.htm#productn> Sugar cane is a member of the grass family. The sugar cane has hollow stalks filled with a sweet juice or sap from which sugar can be extracted and can grow to 15 feet tall. It grows best in very warm climates and is ready to harvest after 10 to 20 months.
The Cotton Gin was the first machine that separated the actual cotton from the cotton seeds of the plant. Cotton production greatly increased in the south. 5. The Compromise of 1850 ended the Mexican-American War. 6.
What early colonial prosperity there was resulted from trapping and trading in furs. In addition, ﬁshing was a primary source of wealth in Massachusetts. But throughout the colonies, people lived on small farms and were selfsufﬁcient. In the few small cities and among the larger plantations of North Carolina, South Carolina, and Virginia, some necessities and all luxuries were imported in return for tobacco, rice, and indigo exports. To conclude, economics was the most important role in the establishment of European colonies.
Prompt A: The Inca Empire was a complex society whose reign lasted less than 100 years. Stretching from the western corner of modern Columbia down towards the center of Chile and Argentina, the Incas occupied a vast area to both the east and west of the Andes. Within this large expanse, its inhabitants drew benefit from the coastal, mountainous, and rainforest climates. The western coast and lowlands afforded maize, cotton, fish, fruit, and shells while the forest to the east of the Andes provided fruit, but also was a good resource for wood, feathers, and coca leaves. The Andes themselves was rich with metal and was the perfect place to grow maize, potatoes, quinoa, and was a good environment to raise llamas and alpacas for their wool.
This diaper was pre-formed and was the first pin-less, snap-on diaper. Between the 1960’s and 1980’s disposable diapers evolved quickly. Instead of using cellulose tissue, a pulp mill was introduced. Using cellulose fibers instead of paper improved the performance of the diaper. Recent years have brought many "improvements" to disposable diapers.
The oldest printed paper currently known to man was one-hundred percent hemp and was used in 8th century China. As I mentioned earlier, hemp was also used to draft the Declaration of Independence and the Constitution of the United States as well. Both of these documents are still preserved today as a testament to the strength and durability of hemp paper. This type of paper is also much more economical as hemp can produce four times as much paper per acre as wood. The process to create the paper does not involve releasing harmful toxins like tree paper processing does.

Hemp Legalization in the U.S “Hemp is of first necessity to the wealth & protection of the country,” said Thomas Jefferson (Hempcar.org). Hemp is another word for the plant Cannabis sativa L. Marijuana also comes from this plant but the strains of hemp used in industrial and consumer products contain only a negligible level of intoxicating substance delta-9 tetrahydrocannabinol, or THC (www.sdearthtimes.com). For over 5,000 years, hemp has been used for textiles, paper, building materials, fuel, food and personal care products. Today Hemp is grown all over the world and used to make over 25,000 consumer products. The plant requires little or no toxic chemical fertilizers, herbicides, or pesticides (Golub 243).
