篇一：Agricultural pollution 农业污染英语作文
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.

Organic food
Nowadays, organic food is very popular with people of all ages, so people are discussing which is better between organic food and traditional food, which is more worthy of being the optimal choice. The advocates of organic food frequently proclaim that such food are safer and more nutritious than others, Is this true? What is organic food? Organic food usually comes from organic agricultural
production systems, according to the International Federation of Organic Agriculture production requirements and the corresponding standard production processing. The main features of the organic food from organic agricultural production systems in ecological good. Organic food production and processing, do not use chemical
pesticides, fertilizers, chemical preservatives, synthetic substances. Therefore, organic food is really from natural, nutrient-rich, high quality and safety environmental ecological food!
What is the difference between organic food and traditional food on nutrition and safety? Studies from the USA have shown that organic food pesticides were below traditional food, and also organic food nutrient content were more than traditional foods, especially organic acids and poly-phenols content. So choosing organic food is more beneficial to people's health, therefore We should try to choose organic food for us and our family.

气候变化损害东南亚农业
Economic damage from climate change will hit Southeast Asia harder than other regions and seriously
jeopardize production of rice, the world's most important food crop, according to a report by the Asian Development Bank.
The report, released Monday in Bangkok, found that the total cost of lost agricultural production and other negative impacts from climate change would be equivalent to as much as 6.7% of gross domestic product in major Southeast Asian countries by the end of this century, more than double the 2.6% loss estimated for the world as a whole.
It also found that rice yields would decline by as much as 34% in Indonesia and 75% in the Philippines, while Thailand and Vietnam, among the world's biggest exporters of the food, would also experience declines.Southeast Asia 'will have to do something' to offset those losses, including making new investments to maintain agricultural production, says Juzhong Zhuang, an economist at the ADB.
The vulnerability of Southeast Asia stems largely from its geography, which includes the vast archipelago of Indonesia and other low-lying nations such as Thailand and Vietnam with long coastlines. Some 80% of the region's population and much of its economic activity are within 100 kilometers (来自:WWw.zW2.CN 爱作文网)of the coast, the ADB said. Southeast Asia's economy also relies heavily on agriculture and forestry, both of which may be affected significantly by changing weather patterns.[来源:学#科#网]
Economists and scientists are still debating how emissions will affect climate in Asia, though generally they agree that weather patterns should become more volatile. The ADB, for its part, said it believes Thailand, Vietnam and Indonesia will experience drier weather over the next several decades, with that pattern possibly reversing later in the century.
Annual mean temperatures in those countries and the Philippines could rise by as much as 4.8 degrees Celsius by 2100 compared with 1990 levels, while sea levels could increase by 70 centimeters.[来源:Z xx k.Com]
Those changes, especially the higher temperatures and a rising incidence of storms, could combine to cut rice yields and otherwise damage crops, the ADB said.[来源:Zxxk.Com]
In debates on global climate change, Southeast Asia has traditionally received less scrutiny than other areas because it remains a relatively small contributor to greenhouse-gas emissions, accounting for about 12% of the world's total. But the region's role as a key supplier of rice and other agricultural commodities means any negative impact on farming could have big ripple effects, driving food prices higher.
Indeed, the ADB report is only the latest in a series of papers arguing that climate changes related to emissions will reduce world food production. The Food and Agriculture Organization of the United Nations has warned of increased risk of crop failures from floods and other weather changes, as well as the emergence of new pests and diseases that only flourish at specific temperatures and humidity.

Some agricultural experts believe Southeast Asia still has room to expand production of rice and other crops, especially in parts of Cambodia and Laos that have traditionally had low yields, but could be lifted by more investment in irrigation and better seed varieties. Rice prices have fallen dramatically this year after spiking in 2008, in part because some countries, including Indonesia, already have boosted production.[来源:Z xx k.Com]
But many economists believe those gains will be hard to sustain in the long run without billions of dollars in new spending on farming infrastructure, and many fear a new surge in food prices could occur once the world economy recovers from its current recession and consumer demand accelerates.
Smith Dharmasaroja, a Thai meteorologist and climate-change expert, said rice farmers might be able to mitigate some damage from weather changes by improving water storage to capture more rain during wet seasons. But there will still 'definitely' be a decrease in rice production as summers become hotter, he said. [来源学科网ZXXK]
