摘要:本文以美国萨利纳斯州为例,解析了农药、杀虫剂、肥料等对土壤和水源的污染,进而探讨了全球环境污染的严重问题。

To initiate, organic products come from organic farming, which is a system of production which seeks to make maximum use of the resources of the land, giving emphasis to the fertility of the soil and biological activity, at the same time minimize the use of non-renewable resources, promoting not to use synthetic fertilizers and pesticides to protect the environment and human health. Organic agriculture involves much more than not using agrochemicals affirmed Raymond Myer, Environment Sciences Professor of Heald College in Salinas California. This includes all agricultural systems that promote the production of organic food with environmental, social and economic criteria, thereby reducing drastically the use of pesticides and synthetic fertilizers, which are genetically modified organisms also emphasized by Mr. Myer.

(Gold) There are countless benefits to opt for organic agriculture compared to conventional agriculture and its use of harmful pesticides that only cause damage to the community and the environment.

 

There is not other effective way to prevent pesticide exposure and to protect fieldworkers is to eliminate the use of harmful pesticides, as an alternative adoption of new forms to growing organic methods. Farmers need to change their mind evading avarice of incrementing their gains and avoiding the use of pesticides. In the other hand the Government need to create regulation which the persuade farmers to adopt of organic production methods. Awaiting that time, community patience must be needed.
