While technology is constantly giving us new ways of doing things, there are some things that stubbornly stay the same. Take the good old cardboard box, for example: 90 percent of all products shipped in the United States are still sent using some type of cardboard packaging. So what happens to all of it once items have been safely removed from their boxes? Unfortunately, they are usually broken down and thrown in the trash or tossed in recycling—but if given a little thought, the possibilities are almost endless. Cardboard can be bent, cut, painted, wrapped, and configured in almost any way you can imagine.  Whether you reuse or recycle cardboard, just be sure that your cardboard does not end up in a landfill! Landfills produce methane and carbon dioxide and break down organic materials. Both of these gases are greenhouse gases, so their release into the atmosphere has detrimental effects on the environment and on our climate. Landfills are also often in marginalized communities, so limiting the effect that landfills have on the surrounding community is important for social justice as well.
