There are conflicting views on the difference between morality and ethics. Some people hold that ethics is objective (for instance wasting natural resources means that they will run out sooner) whereas morality is generated by society (which includes religion as a sociological phenomenon), some that ethics is self-generated and morality imposed from outide; some people reverse both of those. And to make it worse, some define ethics in terms of morality or vice versa, or even regard them as the same (at least one dictionary entry does the latter).

As far as I can see the only way of communicating about either is for each person to define which meanings they are using, and for a discussion group to agree in advance on which definitions they are using and then sticking to them (regardless of the way any individual might use the terms outside that group). Otherwise all you get is noise with everyone misunderstanding each other.
