One significant threat is invasive plant species that are eliminating native plant species. Invasive plants are plants which grow aggressively, spreading and displacing other plants (Ball, 2002). Whether it is intentional or not, they are often introduced by humans. On the other hand, native plants are pants that existed within Pennsylvania before European settlement. Because they are meant to grow here, they are quite beneficial to the environment as well as people (Fell 1995).
These attempts at combating undesirable consequences are evidenced in developing new ways to grow, store, and transport crops in order to get a varied diet to the masses. Improvement in medical science to combat infectious disease, working to combat social and sexual inequality globally and locally. Unfortunately, many of these and other solutions will also come with a cost. It is clear that the development of agriculture came with a significant cost, but to say that it was the "worst mistake in the history of the human race" is an overstatement. It might be argued that the "worst mistake" is not identifying and developing solutions to negative consequences soon enough.

They were able to outcompete their American counterparts and the Amerindians by taking food from them and out-breeding them thus taking up more space. This caused not just destruction to the land, but also a decline and in some cases, extinction in the native plant and animal species. These animals not only had a destructive effect on their new environments, but also permanently altered the ecology of the Americas thus forever marking their spot in history.

This seemed to create an epiphany in the minds of many. There was a new view on land and its worth through agriculture. Up until this point, land was not appreciated for its worth. Wulf explains, “as Americans wilderness became part of the country’s national identity and an object of pride, visitors to Monticello began to appreciate Jefferson’s approach (Wulf, 180).” The Louisiana Purchase allowed for Jefferson to showcase his expertise in agriculture and gardening. Jefferson’s motives were not strictly limited to politics, he aimed to assist the economy from becoming a manufacturing society by promoting westward expansion (Wulf, 159).
Melvin Randolph Gilmore sums this idea up well in the following quote: "The country can not be wholly made over and adjusted to a people of foreign habits and tastes. There are large tracts of land in America whose bounty is wasted because the plants which can be grown on them are not acceptable to our people. "(Gilmore 1977). Native Americans learned about the plants in their environment through general trial and error and through communication with other tribes (Gilmore 1977). Some of the dyes used by Native Americans of the Missouri River region are discussed below.
Farmers can simply apply the weed killer to a crop field, killing the unwanted plants and leaving the food crop unaffected. For example, GM oilseed rape the source of canola oil is resistant to one of the chemical that are widely used to control weeds. The same process can now be done with genetically modified wheat crops hence this will save time and money that has previously be needed to be spent. One of the harder things to get right in ... ... middle of paper ... ... and efficiently through the diet. Over-Use of Herbicides The planting of herbicide-resistant crops might encourage farmers to use weed killers more freely, since they could then be applied indiscriminately to crop fields.
The Enclosure movement had two important results. First, landowners tried new agricultural methods. Second, large landowners forced small farmers to become tenant farmers or to give up farming and move to the cities. Jethro Tull was one of the first scientific farmers. He created an invention that dug deep seed sized holes, which helped more seeds take root and boosted crop yields.
Non-native species is a term commonly used to refer to plants and animals introduced to a foreign environment mostly by humanity either intentionally or accidentally.. Such exotic invaders die because they cannot adjust to the introduced ecosystem, which implies they entail domestication. However, some thrive to the extent of dominating their new ecosystem by spreading quickly and widely. These kinds of invaders do not have their native predators and with time take over the ecosystem from native species (David and Sweeney 53). The term invasive can refer to introduced species and diseases as well.
With close observation, they soon learned the characteristic of plants, and started selective domesticating the plant that were beneficial to them and the climate of that region. “They removed unwanted plants through weeding and selected the seed they planted in order to get crops that had favorable characteristic…certain crops became domesticated, that is, modified by selective breeding so as to serve human needs” (page 7. History of western society). Since, farming required long working hours and more labor, early farmer who relied on agriculture were less nourished then foragers. Although, less yield had resulted more health complication on early farmers, but also more people start farming.
Members of these societies lacked nutrients found in crops unavailable to them... ... middle of paper ... ...crops to find the most productive varieties, the naturally-occurring diversity provides more protection against insect and climate harm, as each crop will adapt to the environment it is in. If people take only what is needed from the environment, not more, this will ensure the retention of the world and its countless societal groups further into the future than relying only on modern technology, which in fact is less productive and more harmful. What the people of the Gamo Highland region are teaching the rest of the world is that there is an important connection between the self and the environment, and in order for the landscape to be the most productive and helpful to the people in it, this relationship must be closely maintained. This will help alleviate the negative aspects of agriculture, enhance the positive outcomes, and overall improve the standard of life.
