to pop into a reusable container. Instead of wrapping your sandwich in aluminum foil or plastic wrap, find a really nice container for keeping your sandwiches all tucked in and in one piece. You'll be amazed to see how many different options there are for keeping things fresh and contained.
The best thing I have discovered about going litter-less is that every morning I get to play Tetris while I stuff the lunch kit with all the food, trying to get everything to fit nicely. So far, after two months of going litter-less, I have always been able to fit everything in; and I pack a lot of healthy food as my kids are ferocious eaters! SO what are you waiting for? Make the change now, and reap the rewards in the years to come. You can even set up a reward system for your child for not loosing any containers throughout the year: a special sushi dinner or a year end movie. Explain to your kids why you are going litter-less and ask them for their help to be held accountable too. They will feel proud knowing they are doing what they can to make a difference in our environment. And the parks and playgrounds will be cleaner too!
