Agriculture Farming methods were primitive and ineffective in the early part of the Middle Ages. At planting time‚ peasants tossed out seeds and plowed fields. Only few plants grew and yields were low. However‚ people gradually adopted new methods and technology. A new farming method was developed. Improvements in agriculture began in 8th and 9th century CE and became widespread in the year 1000. One advancement was the three-field system‚ a method of crop rotation. On the manor‚ there

(“Factory Farms‚ Adverse Effects of.”) The availability of feed and the discovery of antibiotics have both helped factory farming grow as an industry. (“Factory Farms‚ Adverse Effects of.”) Feed has become easier and cheaper to purchase because of the use of synthetic fertilizer and the large numbers of it that are being produced (“Air Quality”).

If the remaining 99% of the animals raised in factory farms in the United States were instead raised in a free range system the increase in resource demands would be incredible. For example‚ cows in todays factory system are raised on a supplemented diet of corn and therefore require no pasture land. If instead‚ all of the 30.2 million cows killed annually were raised on a natural diet of grass it would take over 60 million acres of pasture to accommodate the animals. That is a area of land roughly

Being able to extract a compound or substance from a product or object will encourage us in being able to do the same in a similar manner with a tea solution. Extracting compounds is an important step in any kind of organic chemistry lab and will help us be better at accomplishing the experiment in a much faster and accurate rate than from before. Experimental To begin the experiment‚ a tea solution must be made by incorporating a tea bag into a beaker filled with almost boiling water and the
