Answer 2

1. Canning

In the past, the arrival of fall meant a scramble to harvest and preserve as much food as possible before the cold weather set in. Most families would spend many long hours working on this enormous task because their year-round access to food depended on it. Only in recent decades have we become reliant on the convenience of refrigerators, which are wonderful for keeping food fresh -- until the power goes out. Then a mad scramble of another sort ensues – trying to eat as much of the food before it goes bad within a day or two


2. Drying

Drying is considered to be the easiest and least labour-intensive way to preserve food. Since mold, bacteria, and mildew thrive in a moist environment, drying is effective for food storage because it removes all water and can be stored safely for a long period of time. You can buy a food dehydrator or use a low-temperature oven, although the latter can take many, many hours to accomplish the task.
