Public Transportation

I need to create an argumentative essay based on this: The government makes the claim that using public transportation has positive effects on the environment, however, in South Florida, efforts to develop more efficient public transportation has been less than successful.

My thesis is:  Public transportation is a system that greatly benefits the environment which is why Florida should be finding innovative ways to improve its public transportation policies.
