People in the United States spend more time and money shopping than anywhere else in the world. All these purchases certainly don't make the planet a happier place. Every single thing you buy has an environmental impact. Some are much bigger than others depending on how they are made, how much they are packaged, how far they are shipped, what it does, and what happens when we're done using it. One of the most important — and least expensive — choices people can make to protect the Earth is to buy and use less stuff.
