Although April 22 is "officially" Earth Day, everyday deserves to be earth day, and there are many ways to embrace it-including exchange traded funds (ETFs). There are now ways to drive green, with hybrid cars; you can shop green, now there are energy efficient TVs, refrigerators, computers, lawn mowers and light bulbs that use less energy; act green by volunteering time, support a charity, or even plant a tree. And you can invest your green into a "green ETF". Wall Street has become the newest focal point  for environmentalists to seek help and there has been ample response. XShares, with the Chicago Climate Exchange are creating investable carbon emissions credits for companies who pollute while producing.

One ETF that selects companies who are environmentally and socially responsible is the iShares Select Social index Fund (KLD). This fund holds 218 companies from the Russell 1000 and the S&P 500 that has the highest socially and environmentally sound scores. Whether you invest your "greenness" or act on it, make sure and enjoy your beautiful Earth.
