Three actions to reduce global warming

• Use fossil fuels more efficiently
• Save old-growth forests, cut sustainably
• Plant trees when you travel
• 1 tree every 2,000 miles (3200 km) by car
• 1 tree every 1300 miles (2000 km) by plane
• 1 tree every 100 gallons (375 liters) of gasoline
• 1 tree every 1000 kilowatt-hours (one kwhr ~= 1.9 pounds CO2)
