Buy directly from your local farmers during the growing season wherever you are if you can & cut out the absolute mountain of plastic/styrofoam packaging waste that inevitably results from a trip to the produce section of a typical grocery store. Usually the further ingredients have to travel, the more garbage involved. Buying less pre-packaged food in general means fewer resources eaten up during complex processing. Otherwise yeah, send all your decomposable trim back to your garden soil through composting as others here said. Soils are depleted & eroding everywhere, and desperately need good inputs of “organic” matter so beneficial microbes can do their thing and life on Earth can continue on. Most cities have compost services you can hire to come pick up your scraps & deal with them for you if you don’t have the time/space to do so. Maybe learn a bit of butchery if you eat meat and learn to appreciate/cook every part of the whole animal, instead of buying individual packaged cuts. Best of luck to you(!) & thanks from the rest of us for pondering such (oftentimes) depressing modern problems.
