If we use electric car instead of cars which run on fossil fuels,we can reduce use of fossil fuels.Hence, this car technology can be employed to conserve the fossil fuel reserves. Hybrid car technology uses two or more distinct power sources to move the vehicle.
Use of biofuels such as ethanol or biodiesel could also play an important role in saving fossil fuels. Ethanol is is the most common biofuel worldwide. It can be mixed with gasoline to any percentage and used in existing petrol engines as a replacement of gasoline. Biodiesel is beneficial because it can be used in existing vehicles with little or no adaptation.
Solar panels can be used in homes instead of electricity which is generated using fossil fuels.
Using mass transportation like train,bus,metro instead of personal car could reduce the use of fossil fuel.
Using alternate energy sources like solar power,tidal power ,wave energy,wind energy,hydro thermal energy ,geothermal and nuclear energy could definitely reduce the use of fossil fuels.

"Mesoamerica"<em> (Middle America)</em> refers to the ancient civilization of Mexico and Central America. This included the <em>Aztecs, Mayans, Olmecs, Zapotecs, Mixtecs and Teotihuacans. </em>
These civilizations were able to independently survive on their own by using advanced techniques. For example, the Mayans made a system of calendar known as<em> "Maya calendars." </em>This is because they were attracted to the<em> cycle of time.</em> Another example are the advanced tools made by the Aztecs. They were even able to make <em>drills </em>(bone and reed). Their agricultural systems were very complex.
