Agricultural activity is the earliest human’s activity on the natural ecosystem. It not only changes the local natural ecosystem but it also has a huge impact on the ecological environment. When many scholars trace back the historical roots of the problems of ecological environment, naturally they will be concern about the traditional mode of agricultural production, even back to the age when the foundation of traditional agricultural technology system was formed. Agricultural development for thousands of years both created a splendid civilization, but also accumulated a lot of environmental problems. The negative effects both affect the prevailing agricultural production and left some bad condition to future generations. In this paper, the whole process of the impact of human activities on natural ecology was discussed to provide more adequate historical basis for future environmental protection.
Impact on the ecological environment of ancient agriculture
In primitive societies, many forests were destroyed. People deforested to stave off the wild animals, develop farmlands and build houses. The disafforestation caused great damage to the forest and the animals inhabited there. Easter Island once had lots of forests. There are a lot of statues made by stone in Easter Island (Hughes, 102). Sculpture and transportation required a mass of mainpower and resources. Therefore, the subtropical forests in the island disappeared after deforestation. There were no raw materials for shipbuilding and transportation of the statues and no edible wild animals because of the extinction of tree species. In 1774, Europeans came to the island, kidnapped natives as slaves, brought infectious diseases such as smallpox and introduced shee...

...ulgated in many countries, which play an important role on the protection of agricultural ecological environment. The "ecological agriculture" is a new type of agricultural production systems which is that the modernization of agriculture will go into a road with reasonable ecology and will achieve sustainable agricultural development. The "ecological agriculture" is the only way to promote the sustainable development of agriculture in modern world.

- ... There is a literal and physical separation from the environment within the machine workers, which in turn, causes a shift in their minds as well. Principally, atop a tractor, a human becomes insensible to connection with the land, and the land becomes nothing more than a source of profits. The human becomes ignorant and can no longer recognize how the Earth beneath and around them is changing, for better or for worse. However, atop a horse, a human may feel life, invigoration, and the true spirit of Earth within his body.... [tags: Agriculture, Human, Natural environment]

- Mimicking the Natural Environment In Clifford Geertz’s article, Two Types of Ecosystems, he suggests that the uneven distribution of the Indonesian population is in direct correlation with the different methods of agriculture used by those in the densely populated area and those in the less populated area. Geertz explores the distinct characteristics of two methods of cultivation in Indonesia, swidden and sawah agriculture. Swidden agriculture, as described by Geertz, is when the forest is burned and cleared so new crops can be sowed.... [tags: Agriculture Nature Essays]

- This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands. - Barack Obama This quote taken from a speech that Barack Obama gave whilst running for the presidency will go down in history as an embodiment of the vision of hope and change that gave life to his campaign. It also is an explicit reference to anti-global warming movement. Although the sentiment is profoundly noble it is rather interesting that famine is presented in the same vein as sea rise and storms, that is to say presented as a direct result of environmental issues....

- Background Agricultural methodology and process has been improved and benefitted with new technologies. Precision Agriculture (PA) definition is evolving with technology development. Most precise definition may be “The application of technologies and agronomic principles to manage spatial and temporal variability associated with all aspects of agricultural production for the purpose of improving crop performance and environmental quality”. PA is conceptualized by a system approach to re-organize the total system of agriculture towards a low-input, high-efficiency and sustainable agriculture....

- What is a Sustainable Agriculture. To define the sustainability of agriculture, we must look into the several relationships agriculture has with the basic nature of making something sustainable. In this research literature, we will look at the factual information regarding agricultural practices as they relate to the long-term stability of biodiversity, ecosystems, and Natural resources. We will also compare historical and modern perspectives of economics as they relate to resources and sustainability.... [tags: Environmentalism / Economics / Agriculture]

- Effects of Agriculture on the Environment Introduction: Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre. Humans, like all other species, exploit their surroundings for the resources they need to survive.... [tags: Agricultural Environment Nature Essays]

- ... Environmental surroundings get to be divided when technological advancement splits up areas of land. Some examples of this can include streets which may slice through woods or even trails which wind through prairies. While it may not sound all terrible on the surface, there are bad results. The biggest of these results are felt by particular animal and plant groups, the vast majority of which are specific for their bio-region or need a large area in order to make sure that their genetic lines are kept intact....

- To consider the human condition apart from the natural environment is both foolish and inconceivable. It is in unity with a modern mode of thought that humans are raised to think that they are in some way separated from their natural environment. In developed society the weather has become nothing more than something to discuss with the person standing next to you in the checkout line.

- Agriculture was fundamental to prehistoric societies and an addictively trend that eventually replaced hunter-gathers societies. It has become debatable if agriculture produced Jordon Childe’s ‘Neolithic Revolution’ or that it served ulterior purposes in religious and social agendas but it is certain that it spread across the world possibly through natural cause or the direct influence of human activity. In the case of Mesoamerica these debates tend to favour agriculture as a revolution to improve sustenance and result from both the intentional actions of humans and the natural environment that endorsed productivity....

- Mark Luccarilli gives a concise review of Bill Bryson’s A Walk in the Woods that is published in Terrain.org Issue No. 5 in autumn of 1999. Throughout his review he mentions many times that Benton MacKaye’s original ideas for the Appalachian Trail have not been implemented and that the trail itself could be considered a failure by MacKaye’s terms. Luccarilli acknowledges the fact that the United States, as a whole has failed to create a middle ground incorporating agriculture and nature, and he also explicitly states that, “The notion of a pastoral city may strike us as utopian folly at its height” (Luccarilli 2)....
