Panel discussion (help for a poor german girl^^)

In school we are going to have a panel discussion about globalization and we all play a role. I am a moderator and my problem is what can you ask if discussion stops? We have a guy from greenpeace, one who owns for example BMG, one who works for McDonalds and one normal worker...
At first my introduction (maybe you can help me with some improvements)
"Welcome at our todays panel discussion about globalization. We are (our names) and want to show you different opinions about this topic. Today our guests are (then I say their names). Please introduce yourselfs nd tell us briefly if you are pro globalization oder con and why you think in that way you do"

But maybe theirs an acutal happening which is connected with globalization or you have only an idea to help me a little bit...

Thanks for reading
