Protests to save Bulgaria's Pirin National Park , a UNESCO World Heritage Site , from construction activities have continued within Bulgaria and around the world in new and creative ways to get their message across.
In December 2017, the Bulgarian government approved a plan to allow construction in 48% of the park, which is home to numerous threatened flora and fauna species and considered one of the country's natural treasures.
The controversial decision, which opens the door for the expansion of a ski resort there, sparked widespread criticism, with environmentalists arguing that it violates the park's status as a protected space.
Thousands of Bulgarians  have hit the streets of Bulgaria's capital Sofia every Thursday to demand that the park be protected. The protests have attracted environmentalists, mountaineers, families with their children and pets, and people who practice winter sports, as well as a variety of artists including traditional musicians, samba musicians and circus performers.
Some participants have shown up wearing traditional costumes, while others have sported provocative makeup  and even three-meter-tall butterfly costumes.
The actions aren't limited to Sofia, but continue to pop up in different cities each Thursday  across Bulgaria and abroad, including Stockholm , Sydney, Skopje  and Glasgow, mostly organized by Bulgarian nationals in diaspora. An online map  shows visually these spots of active citizen mobilizations, where anyone can add their own point of support geographically.
Those rallying to protect Pirin National Park, citizens and organizations alike, have employed artistic means to express their displeasure with the Bulgarian government's decision. For example, international NGO World Wildlife Fund prepared 21 jars to representing the “last bits of clean air” from the park:

21 jars with the last bits of clean air from Pirin, one for each Bulgarian government minister! #SavePirin
Music and song
This was not the only creative act in the rising wave of opposition. People have made use of music in a variety of ways.
Bulgaria's national anthem actually references  Pirin:
Slantse Tkrakiya ogriava,
Nad Pirina plamenei
Over Thrace  the sun is shining,
Pirin looms in purple glow.
The verse now adorns the cover pictures  of many Bulgarians’ Facebook accounts, not so much as a sign of patriotism, but rather as a riot against their own government.
Playing in the background is the famous song “You are beautiful, my forest,” which is often associated with environmental protests in the country. The haunting piece, sung a capella, tells of the sadness of losing beloved nature and never getting to see it again.
And in Prague, protesters even used the public piano  of the railway station to deliver their message using music:
Running and biking
In one of Bulgaria's cities, Razgrad, a local group of runners and bikers regularly comes together in evenings to practice their sport. They did it once again on a cold January Thursday, but this time, they wore messages  to save Pirin on their clothes.
A larger relay marathon titled “Run for Pirin ” is in the works to connect some of the towns protesting in the country, carrying their messages in the relay itself. Its creator, Ognyan Hristonev, found inspiration in Romania's recent wave of anti-corruption protests  that brought hundreds of thousands people  to the streets – amongst whom were walkers who had traveled from the other side of the country . He noted:
Groups of Romanians walked up to 450 km on foot to call for a just leadership of their country, one that would truly serve its people. This effort of theirs inspired so many other people to get out of their couches and go protest.
I may not be in my best shape now, but I would run and even crawl to get to Plovdiv [one of the towns protesting to #SavePirin, more than 150 kilometers away] and pass on the relay.
Soup and spirituality
A bit to the west, in the town of Pleven, people gathered together to cook and eat soup together and watch a live concert , all in support of #SavePirin. The event was inspired by the international movement and film HumanSopa. 
Even more spiritual was an initiative taken up by nature lovers, who chose to use meditation. They set a date and time for a “Group visualisation for the protection of Pirin and consciousness on Earth “; regardless of where people were located, at the same time they directed their thoughts and positive messages towards the preservation of the mountain range's nature.
Hristo Valchev, an activist in environmental education who is affiliated with Naturalistichno.org , is at the heart of this visualisation. He wrote:
We know our roots with the Earth and understand our part of the whole ecosystem of the planet. We wish and send best vibes so that everyone else understand their roots and part of the Gaia-Earth. […] We hope that you will understand us and join the action for the holy good of all!
All of these different actions are examples of grassroots movements that citizens are undertaking in a system they feel doesn't respect their will. Of course, many other behind-the-scenes moves are needed if an effort like this is to be successful, such as filing legal objects or invoking other institutional resources.
But the statements and street demonstrations of support not only give strength to the frontline activists fighting to protect the park, but they also increase public attention to ensure that the not-so-visible actions don't end up buried in a drawer somewhere.
