Growing up in a society that had a limited selection and shortage of certain foods, I became more aware of what food represents and what is its real value. Both of my grandparents had small farms with several domestic animals, and as a kid we used to help out in the garden and in the field a lot, weeding out vegetable beds, planting seeds, picking fruits and even digging out potatoes. The appreciation for our meal was that much greater, and we enjoyed every bit that was on the plate.
Things have changed tremendously in those 30 years; developed countries produce twice the amount of food their population can consume (see data source) and waste a big portion for it without any justification, while over billion of people on this planet goes hungry every day, according to the latest United Nations report.
After over a decade of living in a small Manhattan apartment without any possibility to grow anything besides herbs on my window sill, I finally have a house and a garden big enough that I can grown my own fruits and veggies, at least some of them. And although time for my garden is quite limited, our produce saves us a substantial amount of money every month from not buying organic or farmer's market produce. It also helps our kids and friends to understand the value and origin of our food and teaches them to enjoy it, appreciate it and not to waste any food.
