Abstract

Currently, there is an increased global interest in influences and consequences of some agricultural activities performed to improve the production level, like increasing amount of inputs such as chemical fertilizers, herbicides, pesticides, etc. on the environment and society. Furthermore, wastewater produced by washing stockyards and chicken farms create a large and widespread area covered by different kinds of pollutions.
It has been estimated that less than 1 percent of poison used in America is practically used for pests and the other 99 percent are wasted and released in the environment. 20 years ago every extra ton of fertilizer would add 15 to 20 tons to the global crop production, but today the same amount of extra fertilizer increase the production by only 5 to 10 tons (Hosseini, Shariati, Jihad Sh 258).  Environmental factor is one of the factors that should be considered in rural development, as preserving the environment and its values in the face of various pollutions and destructions is very important. In performing rural development plan, soil and water degradation must be avoided with all means.
The present article studies and investigates environmental issues like soil erosion, forest degradation, chemical poisons and fertilizers, etc. in rural development. Afterwards, the importance and necessity of biological issues in rural development, case study and finally the consequences are analyzed.
