Study: Ethanol May Add to Global Warming

I am a college student and former entrepreneur and I manage investments for friends and family. I've been managing other people's investments for 6 years and during that time attained an annualized return of 41% in US dollar terms and 33% in Canadian dollar terms (as of 03/22/2009). My current area of focus includes technology platform companies. I am also heavily tilted to the internet and emerging markets. From 2003 to mid-2005 my portfolio was weighted largely in gold mining investments. I then switched into Chinese equities. Both of these macro strategies payed off and have contributed to the bulk of my returns.
