How should customers make final choices?

It is often said that buying food grown at local farms is a better choice than buying from a supermarket or grocery store.
But is this true? Many farmers forgo the use of chemical pesticides and fertilizers. Many say that, for this reason, locally grown food is healthier and fresher than the produce you get from your local supermarket, and that it tastes better too. Buying vegetables at a farmer’s market, they say, is also better for the environment if you compare it with buying the same vegetables from the local grocery store; these have very likely been packed and shipped months before. It’s a simple idea—the shorter the trip from the farm to our plate, the fresher and healthier our food will be.
And there’s no journey that’s shorter than that of the fruit and vegetables at farmers’ markets, which as the name suggests are physical markets where farmers sell fruit, vegetables, eggs, meat, and sometimes even preserves and beverages directly to consumers. In Canada, farms sell a variety of organically or locally grown produce, such as kale, several different types of fruit and vegetables, such as strawberries, raspberries, oranges, apples, cherry tomatoes and Romano tomatoes, egg plants, green pepper, beetroot, lettuces, spinach, honey, and maple syrup. The farmers’
markets are also found in flea markets in Canada.
