Turn off your car when you stop for more than ten seconds

How this helps wildlife: 

Turning off your car might be the easiest way to reduce your vehicle's impact on the environment. Idling not only wastes fuel, it creates greenhouse gas emissions and other pollutants that affect wildlife worldwide. Turn off your car whenever you stop for more than ten seconds at airports, bridge and railroad crossings and schools. The one exception is when you're in street traffic, where stopping is illegal in some states due to safety concerns. Instead of waiting at drive-thrus, park and go inside.
