It is argued that countries should grow crops for their own residents and confine imported food as much as possible. From my perspective, I completely agree with this idea.
There are different advantages of national food self-sufficiency. Firstly, native cuisines can guarantee food security, which is a prior option when people purchase food. This is due to the fact that the government can oversee food manufacturing procedures. Therefore, ingredients will be ensured to be clean and fresh, also not contain any toxic preservatives, which are the culprit of serious health problems. Secondly, since commodities are produced by national manufacturers and be moved straight to consumers, residents can enjoy local staples with lower prices. Unlike imported merchandise, people need to pay extra costs for long-distance transportation, which is a contributor to the proliferation of original food prices.
Besides, countries should also constrain imported groceries by some specific reasons. The first reason is that they can alleviate food miles, which may breed the deterioration of global warming. As a result of less food being transported, they can descend the carbon footprint and mitigate climate change. In addition, these countries may not be dependent on foreign counterparts in terms of food supply. There will be some severe circumstances that exchange countries are unable to export their foodstuff, which affects the indispensable demands of local inhabitants. To illustrate, in the recent pandemic COVID 19, when all transactions were prohibited, Australian could not be catered for tropical fruit from Vietnam, hence, it may disturb their eating habit.
To conclude, I firmly believe that countries should produce staples for their own population and be self-reliant form other countries in terms of imported food.
