Agriculture and the Natural Environment

– Introduction 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….  

Effects of Agriculture on the Environment

– 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….  

Energy and Industrialized Agriculture

– Agricultural practices throughout the ages have evolved dramatically. Having started off as simple pastoral management and shifting cultivation, these methods have been altered substantially in the name of “progress”, primarily in the US and other industrialized nations. Through this progression the energy inputs and outputs has been drastically altered. The industrialized food system as we know it is much more complex today than the simple agricultural practices used thousands of years ago. Today, the industrialized agricultural system is dependent on extraordinary amounts of fossil fuel inputs in order to maintain its complexity….  

Science and Technology in World Agriculture

– … This is effective because he correctly assumes that his readers have opposing views about agriculture, thus having a different understanding about the nature of narratives. This assumption does not really support the evidence to establish common ground. Yet, it helps readers to better understand the nature and impact of contrasting narratives in agriculture. After establishing common ground, Scandizzo unites both conservative and radical parties by using the evidence of the ecological problem caused by current agricultural practices….  

The Effects of Pesticides on Agriculture

– The growing demand for enhanced food productivity to meet the needs of the global population has led to use sophisticated agriculture technology in which pesticides play a crucial role. Pesticides are extensively used to increase agricultural products by preventing, controlling, or lessening the damage caused by a pest (John et al., 2001). Pesticides have been widely used througout the world since the middle of the last century. They are mainly used in agriculture and animal production, both including substances with high toxic effects and persistance in the environment (Beyer and Biziuk, 2008)….
