Even if your company doesn't celebrate Earth Day every day of the year, there are plenty of ways you can show you're green. Entrepreneur Robyn Rhodes, who we featured in our March article, Confessions of Workaholics, found a way to integrate Earth Day into her jewelry design company.

Rhodes' ecological awareness campaign donates 20 percent of the proceeds from the sale of her Rumi necklace to Global Green USA. Model and actress Josie Maran is the face of the campaign and a supporter of Global Green. The necklace, Rumi, is named after Maran's youngest daughter as a symbol of future generations.
