　　范文：

　　Thanks to the efforts of mass medias, modern citizens are increasingly aware of the severity of environment problems. Facing the worsening conditions on earth, people have adopted various methods to protect the environment, such as giving up driving, recycling objects and buying local organic food. In my mind, the last one is the simplest but most effective solution that we common people can take to preserve environment.

　　In the first place, for the cultivation of organic food, farmers are strictly restrained to use fertilizers and pesticides which contribute a lot to pollution. It is true that fertilizers and pesticides can help farmers increase yields and reduce costs. In the long term, however, many chemical elements are left in soil and drain to local water system, like underground water and rivers. The accumulation of those chemical elements is detrimental to local ecosystem, as some small animals, such as fish and frog, may take in and store them in their body. In addition, while killing harmful insects, pesticides are also poisonous to birds who prey on them. So, it is fair to say that if more people buy local organic food, there will be fewer fertilizers and pesticides applied, and therefore less pressure on the environment.

　　In the second place, to decrease the market share of food transported from places far away is to reduce energy consumption, especially gasoline and electricity. We have to notice that the rapid economic development and population growth is burning up our natural resources. The improvement of living standards also exacerbates energy crisis. If local food is actually enough to satisfy people’s needs, the long distance transportation of food is absolutely unnecessary but a waste of energy. Even worse, some kinds of food have to be carefully stored under certain temperature or be frozen. Then, the transportation cost is even higher. For example, fresh tropical fruits transported by air to cities in the northern areas are usually sold at a high price which includes the cost of transportation. Therefore, when we buy local food, we are actually save energy.

　　In the third place, walking and bicycling to work or study place and recycling old objects are not feasible or effective in conserving environment. For some citizens, driving to the office or school is the only choice, as there is no convenient access to public transportation and walking and cycling will cost too much time on the road. In addition, although it is a good habit to recycle old objects, this may generate other problems. For instance, there must be enough space in the room for the storage of old subjects, which is quite inconvenient for people renting a small flat.

　　To sum up, individuals can contribute a lot to environment preservation. Among all the methods discussed above, the purchase of local organic food is the best option.

　　which of the following is the most effective way to protect the environment:

　　1 walking and bicycling instead of driving to work and study

　　2 recycling old objects

　　3 buying locally grown organic food

　　1 步行或汽車

　　利：節(jié)省能源，減少尾氣排放

　　弊：不方便，因為沒有公共交通，或者距離太遠，浪費時間

　　2 循環(huán)利用

　　利：減少資源的使用

　　弊：比較麻煩，而且廢舊物品的儲存占據(jù)太多空間

　　3 購買當?shù)赜袡C食品

　　利：有機食品不使用化肥農(nóng)藥，而化肥農(nóng)藥造成污染;減少食品運輸能源消耗

　　弊：一般比較貴
