I don't think it's an issue of what they've done. I'm sure everyone makes a change to such tourist attractions to aid tourism or nature.
What's weird is that they lie about it. Anyone else would have issued a news article, even a local one, saying the rivers are dry and this is what we have done to save tourism/nature etc etc.
These fucks blatantly hide the truth because it makes it look like everything is perfect. And they do a fine job of it. This country is one one of the finest built bullshit producing machine and it won't change until someone at the top decides to have a change of heart.
