Reduce Gas Use
Reducing the usage of fossil fuels will help save our natural resources. Reduce the number of trips that are needed for groceries and shopping. Combine trips and travel with friends whenever possible. Then when you buy an automobile consider how much the fuel will cost for the life of the vehicle since that cost is very significant over the life of the vehicle not to mention the pollution that you can prevent with a greener vehicle.
This is a critical point for us to sustain our planet.
