Gardening–and no I don’t mean the lawn service you over pay for every month–but real gardening. Harvesting food used to be an essential skill that everyone needed to know. During WWI and WWII, there was a shortage in farmers and thus less food so some countries like the U.S., Canada, United Kingdom, Australia, and Germany, campaigned for citizens to plant produce gardens in private residences. These gardens really helped with lightening up the circumstances of war by boosting moral and helping reduce pressure on the public food suppliers and banks. Could you successfully cultivate a garden healthy enough to harvest? It might be a good idea to learn considering the environmental crisis we are currently facing.
