Forests are always losers at the Olympics, and that’s unlikely to change anytime soon.

For the winter games in PyeongChang, South Korea, virgin forest was destroyed on Mount Gariwang to accommodate ski runs. For the 2022 Winter Olympics in Beijing, a ski run is set to wipe out part of the Songshan National Nature Reserve. And let’s not forget the 240 acres of Atlantic Forest that were leveled for the 2016 games in Rio de Janeiro to make way for a golf course.

For the upcoming Tokyo games, environmental and human rights advocates have been raising alarms about the use of tropical (热带的) wood to build the New National stadium. Activists have fought against such environmental destruction. The damage is often permanent, threatens endangered plants and animals and in some cases, causes conflicts with native people. But frequently the country’s organizing committee, and the International Olympic Committee (IOC) have found ways to make it reasonable — despite a paragraph in the Olympic Charter (宪章) that states that the IOC’s role is to “encourage and support a responsible concern for environmental issues”.

“As it stands now, the IOC has little authority over a city’s local organizing committee, which finally plans the event, ” Chappelet, professor of public management at the University of Lausanne, told Earther. “Even if the IOC is dissatisfied with the way host cities have prepared for the games, they have no built-in systems to watch them so that they strictly follow the Olympic Charter.” The only thing they can do if they’re not happy is to withdraw (= take back) the right to organize the game. “But the IOC could include more enforcement (执行) systems into the contract they make with the host city,” he added. That contract must be signed and obeyed by everyone and those who break it must be fined.

Boykoff, the author of several books on the Olympics, suggested a similar solution. “The IOC could insist that host cities take their ecological (生态的) promises into account first, but instead they look the other way, time and time again,” he said.
