Today, at 6 p.m. local time in Moscow, the 2018 World Cup will begin with a match between host country Russia and Saudi Arabia. This year’s tournament will be the first in which FIFA required that all stadiums be built and renovated with sustainability in mind. Despite this requirement, some stadiums, such as Kaliningrad, have been less than environmentally friendly. Kaliningrad Stadium was built on one of Kaliningrad’s last wetlands, a habitat for rare birds, on October Island. “It was a typical delta island, with peat and a wetland reed-bed.

Theoretically, of course, you can call any swamp a very beautiful and environmentally clean place, but it’s not really correct in relation to the city infrastructure and the cities.”
