Earth Day was first held on April 22, 1970, and it was lead by Senator Gaylord Nelson from Wisconsin.
Nearly 20 million people participated and today, 42 years later, we still celebrate Earth Day, but now, 175 countries celebrate Earth Day.
Earth Day 2012 will also be celebrated on April 22nd (and will be celebrated on that date at least until 2015).
The primary purpose of the day is to bring awareness to environmental issues as well as to focus on reducing, reusing, and recycling.
Of course, proponents of frugality recognize that the things we do to keep Mother Earth healthy are the same things we can do to keep our finances healthy. By reducing, reusing and recycling, we become more financially conservative.
When you buy a used car, shop at garage sales or your thrift stores or hold your own garage sale or donate items you no longer use, you are saving money and keeping items out of the landfill, which is a win-win.
