As reported last week, local residents have held protests in recent weeks in the cities of Orumieh and Tabriz over what they describe as the government's lack of action.
Artists have also joined the protests -- not by demonstrating in the streets, but through their art.
See here for the work of Iranian graphic designers who are concerned about the state of the country's biggest lake.
"Are you sure you want to remove Lake Orumieh and remove its content to the recycle bin?" asks this artwork.
And this one suggests that Lake Orumieh must be kept alive for future generations.
The website Barzaghmag.com, which has posted the artworks, calls on other artists to send their work to be published as part of the online art protest.
