[The Australian Government] shortly after approving the largest coal mine in its history, successfully pressured the United Nations to remove a chapter about the reef from a report on the impact of climate change on World Heritage sites. Australia’s Department of the Environment explained the move by saying, “experience had shown that negative comments about the status of World Heritage-listed properties impacted on tourism.” In other words, if you tell people the reef is dying, they might stop coming.
It's the other way around. If you tell people the reef is dying, they go en masse, which contributes to the bleaching greatly.
