「持続可能な農業は達成されうるか？」というトピックに対してのボディが5つ揃ったので、そのうちの3つを使ってYesの立場で英検1級を想定した英作文を書いてみたいと思います。
イントロ
Agriculture is an essential part of civilization. It is estimated that about 40 percent of our planet is farmland and it is expanding to feed growing populations at the expense of forests, wildlife and water. It is true that the global agricultural system would collapse if nothing is to be done, however, human beings have realized the situation they are in and worked hard to make agriculture more sustainable.
ボディ①
Growing and transporting crops create lots of carbon emissions in the process. Therefore, reducing food miles, the distance between where crops are produced and where they are sold, is significantly important. Vertical farming can be a solution. Vertical farming is a way crops are grown inside a building in the city or in the suburbs of the city. In addition to reducing food miles, there are some other benefits such as a stable food supply all year round and using less water or no pesticides, all of which are critical factors for sustainable farming.
ボディ②
Adoption of technology is also key to sustainable farming. For example, field robots can apply fertilizers in targeted doses. In addition, sensors in the soil can gather data on nutrients and water levels. This information reduces unnecessary water use. All these technologies would help farmers to produce food in a way that works with the environment.
ボディ③
Soil has an inherent ability to capture and store carbon from the atmosphere. This natural process plays a vital role in forming healthy ecosystems and this can be applied to a farming practice. This method of farming is called regenerative farming and the method is spreading all over the world due to its potential not only to improve food quality but also to reverse climate change.
コンクルージョン
As mentioned above, technology has changed farming and farming today, in fact, succeeds in reducing food costs, labor costs and environmental costs.
