Some people believe that countries should produce enough food for their own population and not rely on imports from other countries. To what extent do you agree or disagree?

The idea that every country should produce all of its own food and not depend on imports may sound appealing, especially in times of global uncertainty. However, I strongly disagree with this view, because it ignores basic economic reasons and how food systems really work.每个国家都应生产自给自足的粮食、不依赖进口，这种想法听起来很有吸引力，尤其是在全球局势不确定的时期。然而，我强烈不同意这一观点，因为它忽视了基本的经济原理以及粮食体系的实际运作方式。

Firstly, trying to be completely self-sufficient in food goes against the idea that countries should produce what they are best at producing. Not every country has the right land or climate to grow every crop. For example, a small country like Singapore would find it very expensive to grow staple grains, while Vietnam has fertile land in the Mekong and Red River deltas and has become one of the world's biggest rice exporters. This benefits everyone: Vietnamese farmers earn money from exporting rice, while other countries can buy affordable rice instead of struggling to grow it themselves. If every country had to grow everything itself, this kind of helpful specialisation would be lost, and costs would rise for everyone.首先，追求完全的粮食自给自足，违背了各国应生产自己最擅长的产品这一理念。并非每个国家都拥有适合种植每一种作物的土地或气候。例如，像新加坡这样的小国，种植主粮的成本会非常高，而越南则拥有湄公河与红河三角洲的肥沃土地，已成为世界上最大的大米出口国之一。这对各方都有利：越南农民通过出口大米获得收入，而其他国家则可以购买价格实惠的大米，而不必费力自己种植。如果每个国家都必须自己生产一切，这种有益的专业化分工就会消失，所有国家的成本都会上升。

Secondly, being part of international food trade gives countries protection against problems in their own agriculture. If a serious drought, storm, or saltwater problem in the Mekong Delta damages a harvest, which has happened before, a country can buy food from other countries instead of facing shortages at home. This works both ways: just as Vietnam sells its extra rice when harvests are good, it can also buy products such as wheat or dairy that are harder to produce locally. A strict policy of self-sufficiency would remove this safety net, making countries more likely to face the very food shortages the policy is meant to prevent.其次，参与国际粮食贸易能让各国在本国农业出现问题时获得保护。如果湄公河三角洲发生严重干旱、风暴或咸水入侵等问题而损害收成——这种情况以前曾发生过——一个国家可以从其他国家购买粮食，而不必面临国内的短缺。这种关系是双向的：正如越南在丰收年份出售多余的大米一样，它也可以购买小麦或乳制品等本地较难生产的产品。严格的自给自足政策会消除这种安全保障，使各国更有可能面临这项政策本应防止的粮食短缺。

In conclusion, although wanting to rely only on your own country for food is understandable, the benefits of international trade, such as efficiency, specialisation, and protection from local problems, are much greater than the safety that isolation seems to offer. Vietnam's success as a rice exporter shows that a country's food security depends on producing what it is good at and trading for the rest, rather than trying to be self-sufficient no matter the cost.总之，尽管希望仅依靠本国生产粮食是可以理解的，但国际贸易带来的益处——如效率、专业化分工以及对本地问题的抵御能力——远远大于孤立自守看似能提供的安全感。越南作为大米出口国的成功表明，一个国家的粮食安全取决于生产自己擅长的产品，并通过贸易获得其余所需，而不是不惜一切代价追求自给自足。

The view that every country should aim for complete food self-sufficiency, rather than relying on imports, has clear emotional appeal, particularly during times of global instability. I disagree with this view, however, as it overlooks important economic principles and the practical realities of how food systems actually operate.认为每个国家都应追求完全的粮食自给自足、而非依赖进口的观点，具有明显的情感吸引力，尤其是在全球局势动荡的时期。然而，我不认同这一观点，因为它忽视了重要的经济原理以及粮食体系实际运作的现实情况。

Firstly, a policy of total food independence conflicts directly with the idea of comparative advantage. Not every country is equally suited to producing every type of crop; a land-scarce country such as Singapore would find it extremely costly to grow staple grains domestically, whereas Vietnam, with its fertile Mekong and Red River deltas, has become one of the world's leading rice exporters, sending millions of tonnes abroad each year. This arrangement benefits both sides: Vietnamese farmers earn valuable export income by focusing on what their land does best, while importing countries gain reliable access to affordable rice they could not easily produce themselves. Forcing every country to grow everything it consumes would sacrifice this kind of mutually beneficial specialisation and push up costs for everyone involved.首先，完全的粮食独立政策直接与比较优势这一理念相冲突。并非每个国家都同样适合种植各种作物；像新加坡这样土地稀缺的国家，若在国内种植主粮将付出极高成本，而越南凭借湄公河与红河三角洲的肥沃土地，已成为世界领先的大米出口国之一，每年向海外输送数百万吨大米。这种安排对双方都有利：越南农民通过专注于自身土地最擅长的产出赚取宝贵的出口收入，而进口国则获得了本国难以自行生产的、价格实惠的大米的稳定来源。若强制每个国家都自行种植其所消费的一切，这种互利的专业化分工就会被牺牲，所有相关国家的成本都会上升。

Secondly, taking part in global food trade provides valuable protection against domestic agricultural problems. Should a severe drought, typhoon, or saltwater intrusion damage a harvest in the Mekong Delta, as has occurred periodically in recent years, access to international markets allows a country to make up for local shortfalls rather than face shortages at home. This works in both directions: just as Vietnam exports its surplus rice during good years, it can rely on regional and global supply chains for goods it cannot easily produce, such as wheat or dairy products. A rigid insistence on self-sufficiency would remove this safety net, leaving countries far more exposed to the very food insecurity the policy claims to prevent.其次，参与全球粮食贸易能为应对国内农业问题提供宝贵的保护。倘若湄公河三角洲遭遇严重干旱、台风或咸水入侵而损害收成——正如近年来周期性发生的情况——进入国际市场能让一个国家弥补本地的短缺，而不必在国内面临粮食短缺。这种关系是双向的：正如越南在丰收年份出口剩余大米一样，它也可以依靠区域和全球供应链获取自身难以生产的商品，例如小麦或乳制品。若一味坚持严格的自给自足，则会消除这种安全保障，使各国更容易陷入这项政策本应防止的粮食不安全境地。

In conclusion, although the desire for national food self-reliance is understandable, the practical benefits of international trade, namely economic efficiency, specialisation, and resilience against local disruptions, clearly outweigh the supposed security of isolation. Vietnam's success as a rice exporter shows that a country's food security is better achieved by producing what it does best and trading for the rest, rather than pursuing self-sufficiency regardless of the cost.总之，尽管追求国家粮食自主是可以理解的愿望，但国际贸易带来的实际益处——即经济效率、专业化分工以及应对本地冲击的韧性——明显超过了孤立自守看似提供的安全感。越南作为大米出口国的成功表明，一个国家的粮食安全若要更好地实现，应生产自己最擅长的产品并通过贸易获得其余所需，而不是不惜代价地追求自给自足。

The idea that every nation should strive for complete food self-sufficiency, forgoing agricultural imports altogether, has obvious emotional appeal, especially during periods of global instability. I strongly disagree with this view, however, as it overlooks basic economic logic and the practical realities of how food systems actually function.认为每个国家都应力求完全的食品自给自足、彻底摒弃农产品进口的观点，具有显而易见的情感感召力，尤其是在全球局势动荡不安的时期。然而，我强烈不同意这一观点，因为它忽视了基本的经济逻辑，也忽视了食品体系实际运作的现实情况。

Firstly, a policy of total food independence runs directly counter to the principle of comparative advantage. Not every country is equally suited to producing every crop; a land-scarce, densely populated country such as Singapore would find it prohibitively costly to grow staple grains domestically, whereas Vietnam, blessed with the fertile Mekong and Red River deltas, has instead become one of the world's leading rice exporters, shipping millions of tonnes annually to countries that could never grow enough themselves. This arrangement benefits everyone: Vietnamese farmers earn export revenue by specialising in what their land does best, while importing countries gain reliable access to affordable rice they would otherwise struggle to produce. Insisting that every nation grow everything it consumes would sacrifice exactly this kind of mutually beneficial specialisation, forcing countries to divert land and labour toward crops poorly suited to their climate, driving up costs for everyone.首先，完全食品独立的政策直接违背了比较优势原则。并非每个国家都同样适合种植每一种作物：像新加坡这样土地稀缺、人口密集的国家，若要在国内种植主粮，成本将高得令人望而却步；而越南则得益于肥沃的湄公河三角洲和红河三角洲，反而成为全球领先的大米出口国之一，每年向那些自身永远无法种出足够粮食的国家出口数百万吨大米。这种安排使各方都能受益：越南农民通过专注于本国土地最擅长的生产而获得出口收入，而进口国则获得了原本难以自行生产、却能稳定负担得起的大米来源。若坚持要求每个国家自行种植所消费的一切，恰恰会牺牲这种互利的专业化分工，迫使各国将土地和劳动力投入到并不适合本国气候的作物上，从而推高所有人的成本。

Secondly, participation in global food trade provides crucial resilience against domestic agricultural shocks. Should a severe drought, typhoon, or saline intrusion in the Mekong Delta damage a harvest, as has periodically occurred in recent years, access to international markets allows a country to offset local shortfalls rather than face scarcity at home. This interdependence works in both directions: just as Vietnam exports its surplus rice in good years, it can draw on regional and global supply chains for goods it cannot easily produce, such as wheat or certain dairy products, ensuring that a single bad season for one crop does not translate into nationwide hardship. A rigid insistence on self-sufficiency would strip countries of exactly this buffer, leaving them far more exposed to the very food insecurity the policy claims to prevent.其次，参与全球粮食贸易能为应对国内农业冲击提供至关重要的韧性。倘若严重干旱、台风或湄公河三角洲的咸水入侵损害了收成——近年来这种情况时有发生——进入国际市场就能让一国弥补本地的短缺，而不必在国内面临粮食匮乏。这种相互依存是双向的：正如越南在丰收年份出口剩余大米一样，它也可以依靠区域和全球供应链来获取自身难以生产的商品，例如小麦或某些乳制品，从而确保某一作物某一季的歉收不会演变成全国性的困境。若僵化地坚持自给自足，恰恰会让各国失去这样的缓冲空间，使其更容易陷入这一政策本欲避免的粮食不安全境地。

In conclusion, although the instinct toward national food self-reliance is understandable, the practical benefits of international trade — economic efficiency, specialisation, and resilience against local disruptions — far outweigh the supposed security of isolation. Vietnam's own success as a rice exporter demonstrates that a country's food security is better served by producing what it does best and trading for the rest, rather than pursuing self-sufficiency at any cost.总之，尽管追求国家粮食自给的本能是可以理解的，但国际贸易带来的实际益处——经济效率、专业化分工以及应对局部灾害的韧性——远远超过了所谓孤立自守的“安全感”。越南作为大米出口国所取得的成功恰恰证明，一国的粮食安全，更应通过专注生产自己最擅长的产品、其余部分通过贸易获取来实现，而不是不惜一切代价去追求自给自足。
