Dear Reader, North American corn (maize) prices have nearly doubled since last Christmas, forcing many Mexicans to find alternatives to corn-based foods like Tortillas. There are many factors at play, but surging demand for corn-based ethanol fuel in the United States is one of the underlying causes for Mexico's recent "Tortilla Crisis."

Our top story this month examines the "biofuel-versus-food" dilemma, and looks into the environmental impacts of large-scale biofuel production around the world. Biofuels also show up in our latest Climate Country Profile of Brazil. The number-one producer of ethanol fuel, Brazil has mass produced biofuels since the mid-1970s and learned the pros and cons of biofuels long before most Americans and Europeans were even aware of the concept.

News to use Speed Kills! Speeding wastes gas and money. Following a few basic driving principles can help you save money and emit less carbon dioxide. According to studies from the Allianz Center for Technology, using the power of your car moderately can save up to ten percent on gas. Drive between 40-60 miles (65-95 km) per hour to achieve minimum emissions. Avoid using air conditioning and use your bike for short trips. Most importantly, when driving at 35 miles (57 km) per hour you are statistically twice as likely to kill someone you hit as when driving at 30 mph (48 km/h). Slow down!
