Mr Grey Face:
As food enthusiasts, we've all noticed the price increases over the past few years, and the rate of price increase is accelerating.
Looking at world events and fertilizer prices makes me believe there will be a food shortage at some point.
Overeating and encouraging it is soooo popular on this website, but I feel I must risk a little ostracism and suggest that we all adjust our lifestyles to not eat as much food.
I encourage buying long-term food like canned food, storing water, and figuring out what foods you can grow. Many "weeds" are actually edible and delicious.
An interesting suggestion to be sure. And one not without merit.
It's not a bad idea to stock up, so it speak. Especially as prices go up and certain foods become unavailable. Cutting back while all of this is happening probably won't hurt.
That being said, growing food is a luxury that not everyone can afford. It assumes you have the land, resources, and time to do this. And if you live in the city, are poor, or are far too busy with other obligations, this may be impossible.
Not to mention growing a few weeds for food isn't really helpful.
It would be better to find additional methods of obtaining food. Some options:
Buy local
Locate a community garden
Befriend a garder or chef
Hunt/fish/forage (or befriend someone that does)
Change up your diet
Buy in-season
Take up canning/pickling (or befriend someone who does)
There are just some examples.
