This is a laughably inept "study".
Almost all the consumption except travel, that occured
would have occured with or without the event. Those
people exist, and would have been eating, generating
waste (and in many cases traveling) anyway.
Keep up the great work enviromorons. You are fully
exposing your agenda, and your utter incompetence.
Thanks for making that point. I was waiting for it. Now add into the equation all of the commerce that was done, (or would not have been done) and all the lives and families that earned income or a salary from the services provided. Enviros disgust me.
