It is reported that China use only 9% of world's farmland to feed 22% of the global population. However, that 9% uses 35% of world's fertilizer and 20% of pesticide. This means agricultural chemicals per unit area are much higher than the world average which leads to agricultural pollution.

In recent years, frequent agricultural pollution occurrences have caused great losses in both national economy and farmers' personal properties. The improper use of fertilizers, pesticide and agricultural mulch could lead to agricultural contamination including water pollution, air pollution and soil contamination. Chemical fertilizers and pesticides bring about water quality deterioration. Residual agricultural mulch leads to soil contamination and endangers the physical characteristics of soil. And incinerating straws increases CO2 levels in rural areas and raises greenhouse gas emission.

Agricultural pollution is non-point source pollution which is harder to control because farmland covers a vast area. But we must do as we can. First of all, the most important thing to solve the problem is to train farmers to use chemicals properly and aware of the danger if do as usual. Secondly, to control pesticide and fertilizer pollution, we should improve the efficiency of pesticide and fertilizer use, so as to reduce the amount of pesticide and fertilizer used in fields. Developing green and organic agricultural production with organic fertilizer instead of chemical fertilizer could do some help also. Thirdly, we should develop recyclable and biodegradable mulch with low cost. In addition, the incineration of straws should be banned nationwide, as straws can be used as paper making, livestock feed, organic fertilizers and so on.

We must make our greatest efforts to control and reduce agricultural pollution for ourselves and our future generation. Let’s start it right now.
