Winter is coming… but what are you going to do with all that zucchini that needs to be used now? You can save food for months – like hitting a “pause” button on it – by freezing or canning, and it just might surprise you how many different types of food can be preserved for long periods of time. 

Below are just a few of many tips and facts on food preservation included in this month’s topic, so visit for more information.

Why are we talking about food waste?

When food is wasted, it wastes all the resources that went into growing, manufacturing, distributing, and transporting that food, too. On a local level, landfilled food waste produces methane, which contributes to climate change. One of the best things each of us can do to take climate action is reduce food waste.
