They say you should drink a lot of water to help acclimate to high altitudes. Apparently, at past Ideas Festivals that's meant handing out a lot of plastic water bottles. Not very sustainable. So this year, the good people at Chevron gave everyone durable water bottles and set up water stations like the one pictured above where we can fill up. Between that and their investment in geothermal energy (they're the world's largest producers) I can't imagine what complaints anyone could have about their environmental record.
