思路解析
这是一道观念类作文，标题跟进口食物相关，这也是雅思写作中比较常呈现的一类话题。审题时候需要注意其中关键词“all population” 和“as little as possible”，可以持对立观念。接下来月半鸭和大家一同梳理下，本国出产食物和进口食物分别的利弊。
首先来看国家自己出产食物的好处。
一是国家自己出产粮食意味着能够提供更多的农业和食品制造业的工作岗位。二是自给自足粮食有助于提本国粮食安全，粮食进口意味着当遇到全球粮食减产、或者国际粮食企业歹意操控价格等问题时，都会对国内形成负面影响，比方粮食价格上升超过居民承受能力，严重的或许还会形成饥荒以及国家安全问题。（如果有考鸭关心时政新闻，一定听到过国内的犁地红线和足量的粮食储备）
可是，不考虑实际情况一刀切的否定粮食进口也有问题。首先是很多国家自身的土地或气候并不具备合格的粮食种植条件，无法实现这一点，只能依靠进口。其次即使有种植条件，给所有人都提供粮食意味着大量的犁地，从经济视点来看，有些犁地其实可以用于种植价值更高或是更加丰富的经济农作物，通过出口这些农作物来交换粮食的进口或许更加划算。
并且，进口粮食自身也有好处，一是丰富本国居民的食物种类，特别是国内无法种植的产物。二是进口粮食，与国内产生竞争或许进一步促进国内相关产业的优化和发展。三是当国内一旦呈现粮食缺少问题，可以通过进口粮食来本国居民的正常生活。

范文示例
In the modern society , there are some people who argue that counties should produce large quantities of food which could satisfy all population’s needs and import food as little as possible. Personally, I totally disagree with the opinion of the topic as imported food is still indispensable for most of countries worldwide.
The first reason why importing is crucial lies in the fact the imported agricultural products substantially enrich the diet of local citizens and improve the nutrition structure. A convincing example is that people in Frigid Zone would by no means have access to tropical food without the export of farm produce. Because of the existence of express transport such as air freight, those people are in a position to acquire a more abundant supply of food and vegetable.
Moreover, this irrational strategy will also seriously undermine the trade balance of import and export, or even adversely affect the relations between countries. This is so because the produces supply relationship of every country in the world is a circulation. Although such move may eliminate the fear of local residents, this will create panic in many countries which rely on exports as the main source of their economy. Worse still, there is a great possibility that these major agricultural countries will retaliate by refusing to import any goods from those nations that have the policy of isolation. Therefore, this proposal is not only irrational, but also irresponsible.
Admittedly, it is undeniable that there are certain risks in imported food, especially during the global spread of coronavirus in recent two years. At present, the re- outbreak of the epidemic in many places in China is due to the fact that the patients eat imported food, especially frozen food, which unfortunately contained the bacteria, and even in the last two months, coronavirus was detected in imported fruits, causing great panic among the masses. However, as long as the customs strengthen the monitoring and control, these risks can be greatly reduced, and due to this the governments have restricted categories of importing and issued relevant policies and new importing standards.
In conclusion, the opinion of the topic is not feasible and the self-sufficiency within a country cannot be achieved mainly because of the limitation of geographical conditions as well as the damage of trade balance.
