The research of organic food
Organic foods are foods that are produced without using modern synthetic inputs such as synthetic pesticides and chemical fertilizers. (Wikipedia, 2011, para. 1). Some people think organic foods are healthier than the traditional foods, some people oppose this opinion. The most important difference between organic foods and traditional foods is the farming method. The different farming methods have the different levels impacts on the environment. Traditional Foods Farming V.S. Organic Foods Farming
Traditional foods are produced with traditional gardening, the production based on hybridizing. Before we use chemical fertilizers, herbicides, and pesticides, the farmers used to use the animal manure to give nutrition to the seeds. The seeds absorb the nutrition from the land and the animal manure to grow up. The traditional agricultural system can classify into “Mixed Subsistence Farming”, the livestock and crops combined into one ecosystem (Biology, 1998, para.1). Organic farming method restricts to use natural pesticides and fertilizers. The organic farming focus on keeping good soil structure and fertility, and the farmers need recycle and compost crop wastes, animal manures, crop rotation, and green manures.(Infonet, n.d., para. 2). The Environmental impact of Traditional Farming
Traditional farming has a vast impact on the earth. Fertilizers and pesticides are major causes of water pollution. The crops can absorb fewer fertilizers, the rest fertilizers will go to the rivers, or the lakes, which will lead to harm the aquatic plants and animals. The pesticides can reduce the biodiversity by destroying weeds and insects. The insecticides and herbicides can pollute fresh water with carcinogens and other poison s that will affect humans and wildlife (World agriculture, 2011, para. 8).
