CAN THOSE CANS
Buy frozen vegetables instead of canned ones.
Pound for pound, canned and frozen vegetables may be comparable in price, but the canning process consumes up to eight times more energy than it takes to freeze, package, and store frozen vegetables. And although most frozen vegetables come in non-recyclable plastic packages, these are less bulky and heavy than steel cans, which take more energy to produce and transport. Frozen vegetables tend to have a more natural flavor than canned vegetables, which are often preserved in a salt solution. Because canned vegetables are usually pre-cooked, they may also have lower levels of nutrients than frozen vegetables, which are usually only blanched before being packaged.
