Why some people insist on spending $3-$5 a day at chain coffee shops will never be something I will understand. I appreciate it as an infrequent treat, but I have a hard time spending that much money every day when I can spend double that and buy a whole pound of beans from that coffee shop and make the same coffee at home. Or you can save even more money and buy a cheaper brand of coffee.
By making your own coffee at home, you eliminate the need for the production of a paper cup, a plastic cover, a stir stick and a cardboard sleeve or holder. That is a lot of waste for one cup of joe.
If you really have to get that coffee at a coffeeshop, consider supporting a local mom & pop business. Studies have shown that 60-80% of the money spent locally will stay local. And while you are there, order the organic and/or fair trade coffee. It generally won't cost you anymore and you are helping minimize your impact on the environment and are ensuring that workers are getting a fair wage.
And while you are at it, don't forget to bring your own mug so that you can at least refrain from creating more waste.
