Dozens of artists in India's Bihar region are painting trees using a tribal art form called Madhubani in order to spare them from being cut down. The Bihar state currently has one of the lowest forest coverage areas in India, coming in at less than 7%. Despite the area's flooding problems due to lack of vegetation, climate change is not a well known subject among the native villagers. This unique project was started in September by local NGO Gram Vikas Parishad and is supported by like-minded organizations.
Because the locals are so deeply religious, seeing depictions of the deities they worship on these trees are likely to incur fear of cutting them down. This is probably one of the few instances of visual art that I've seen utilized in order to literally "save" remaining parts of the environment--potentially a good case study to monitor, especially during the next few flood seasons.
