Preserving Fossil Fuels What Do You Mean By Moral Obligation?

What do you mean by moral obligation? - preserving fossil fuels

We have a mission to convince the Ethics class for a prosecutor in the city like this, create a new plan, which is essentially to prevent and conservation of fossil fuels and the promotion of alternative fuels. Of course there are environmental benefits to this, among others. However, we should make the moral argument. For example: 1) fossil fuel CO 2 emissions) of carbon emissions are bad for us, 3) is morally wrong to inflict harm themselves or others 4) other alternative fuels have fewer side effects, 5) So we have a moral obligation to use of alternative fuels ... something. And I always ask, well, what u mean by moral obligation, why we have a moral obligation to any prejudice to the other and lead ourselves ... and so on. everyone is confused. I wonder what others think, is to understand a moral obligation? Or, as one might say that we have a moral obligation, or not? the use of alternative fuels. I need only a few ideas, because I am determined. Thank you.
