  托福写作素材模板:有机农业的环保益处

  素材段落

  Conventional agricultural practices contribute to water pollution affecting both our health and the environment. Only 1% of the pesticides applied to crops actually reach the pests they target, while the remaining 99% of these chemicals enter the environment. The contamination of soil and groundwater changes our terrestrial and aquatic environment and poses a threat to native wildlife. Many species are dependent on clean water and are now endangered because of contaminants in the water. For example, synthetic fertilizers have resulted in an 8,000-square-mile ‘dead zone’ in the Gulf of Mexico where thousands of fish have perished due to oxygen deprivation. Contradictorily, organic agriculture usually uses animal manures as fertilizers which tend to enhance the soil structure as well as reduce the risk of groundwater pollution.
