Could someone here do the math: how much CO2 is emitted by air travel to Qatar for football teams + entourage + fans vs. European countries hosting the world cup games (e.g. Italy, Benelux, Spain)?
What's more relevant here from an environmental standpoint is the cost of adding lifestyle amenities (water, energy, landscaping, construction, etc) on the ground for the million or so football fans who will descend upon a country not especially designed to handle such a high volume of traffic without committing some serious ecological cost.
