Ah, it is now HATE to say people should use Skype instead of hundreds of people flying private jets thousands of miles to talk to each other.
How dare anyone suggest ways to help the environment, we are NAZI's for doing so!
Sorry, man, have you actually tried to use Skype to get something done? It's awful. Sometimes you need to meet people... and most of those guys fly coach.
But even if you eliminated every private jet, it would only be a fraction of greenhouse gas emissions.
