The main thing I still do for sustainability is grow a good portion of our food. That said, I don’t really do it with sustainability in mind most of the time. It’s really more about quality for price, which is what I base a lot of our decisions on these days.
Gardening I got into originally because I got hooked on the physical labor outdoors. I got super ambitious with the size of it because of ideology, but usually would burn out by the end of the season. I’ve scaled back considerably (only my own 1/10 acre property instead of also an additional 1/8 acre) and focus more on things that grow easily, taste superior to anything I can buy, and that I enjoy growing. The specialization and continuing to advance on my learning curve has me really excited for this season. Hopefully this is the first season I don’t burn out by the end.
Chickens and rabbits I did get into for ideological reasons, both sustainability (mainly the rabbits) and humane treatment of animals (mainly the chickens). I stick with the chickens for that reason, but also because they’re super easy and the egg quality is such you literally can’t buy eggs this good. Not even at the farmers market.
Rabbits don’t save me money and they’re somewhat sustainable. I use commercial pelleted feed because I’ve always run into health problems when I try to substitute in natural forages but rabbit pellets are based on alfalfa (a perennial, if GMO and chemically controlled) and then some waste byproducts of other grains like soy hulls, wheat bran, corn distillers grains, etc. I genuinely enjoy working with them and also feel it’s important if you eat meat to be willing to participate in the whole process.
Not really sure where I’m going with all that, just had some time to share further, hopefully that’s interesting?
