Oil spillages - What about other environment damage factors?

There is lot of concern about BP oil spillage and its effect on environment. But, very little action is seen on the use of fuel guzzlers for which BP and others produce oil. Most inefficient vehicles are produced and used everyday. People say two wheelers are worst environment polluters. I am not able to understand this. A 4-stroke two wheeler gives a mileage of 60-80 kmpl whereas a car gives mileage of 10-18 kmpl. Though, people argue that cars accommodate four persons, it is a normal practice that any vehicle is of single user only and occasionally, it is used for group travel. Thus, two wheelers are better than four wheelers from emission point of view. Further, the pressure on public roads will be less with 2-wheelers than 4-wheelers. Best is public transportation system (rail and bus).

More and more oil is drawn to meet the demands of hungry users. We are using the fossil fuels that are formed over millions of years of formation and projections show that we will consume all these fossil fuels by this century end. That means, in about 150 years (1950-2100) we consume all energy resources that are formed over millions of years with crocodile tears for future generations.

If we are reasonable, then there will not be so called false development / industrial growth with regards to these fossil fuel extraction, refining and usage. Then, there will not be any need for coming up of such greedy corporations who do not care about impact of there misdeeds. Everybody in public pronounce their commitment to save environment but how many practice this.
