I'm mackenzie and I was wondering about airplane emissions because my lego league is studying this topic and we are excepting anykind of answers because we are clueless and competition is in 7 weeks and we have to have this done in the next six weeks but we only have 2 days we meet on and we must finish soon we are very far behind our other group and we don't want to stay that way and if you have any answers please post them for me!!
Thank you,
Mackenzie:):):):)
