Why should people choose sustainable transportation?

There are now around 750 million cars in the world and predictions are that if the present trend continues, the number will double in the next 30 years. All but a very few are powered by petroleum-based fuel.

In 1900 there were just a few thousand cars in the world but as numbers increased, so did the demand for oil. Estimates suggest that during the 20thcentury about half of the world's accessible oil deposits were used up.

It is only relatively recently that people began to be concerned about future oil supplies. A combination of political unrest in major oil producing areas like the Middle East, combined with the fact that reserves are running out in areas such as the US, has heightened this concern and had the combined effect of focusing the mind on seeking alternative energy sources, and pushing up prices.

Added to that, during the last few years people have simply become more environmentally conscious. Whereas before, in many people's eyes the resources of the world were simply there to be made use of, there is now an almost universal appreciation of the fact that the world's resources will not last for ever and that once they are gone they are gone for good.
