I also have a huge collection of cans...coffee cans, bean cans, small large you name it. They are great to have if pots and pans become limited or dirty when the power goes out. Boil water, or even store leftovers till next meal. I know it sounds silly, but when water is scarce anything will work.

You sound like me. I have a complete office full of every container I can find, big or small. Toilet paper/tissue paper/paper towel rolls are awesome. I just fill them with dirt, wait for the seeds to sprout and put the whole thing into the ground. There's so much we can do on our own. It just takes seeds and a little creativity.
