Composting is central to a zero waste routine. Organic matter can't decompose in the anaerobic environment of a landfill and will sit there unyielding forever (guacamole unearthed in a landfill 15 years later was still bright green!). Instead of throwing food scraps into the trash, letting them decompose naturally into rich soil keeps landfills smaller, greenhouse gas emissions lower, and gardens and farms healthier - it's just a really efficient system.
Ideally, the backyard is the best and easiest place to compost - set up a container, learn the basics, and you're set. For me, though, and perhaps for you too, that advice doesn't work: my city apartment doesn't have a balcony, much less a backyard. In case you're in a similar situation, I hope this list of national resources can help you find ways to compost at home and when you're traveling.
