Protesters took to the streets in 29 international cities, accusing the Bulgarian government of corruption and violation of domestic and EU environmental law after it decided to allow further construction in Pirin National Park, a World Natural Heritage site. In December 2017, the Cabinet passed a plan to allow construction activities in 48% of the park — a move that goes against legislation and is seen as a violation of its status as a protected space. After what many felt was the government's failed response to address the public outcry, environmentalists initiated an international outreach campaign in an effort to pressure authorities to uphold the law protecting the natural heritage site. Pirin National Park was established to protect biodiversity in Bulgaria’s second highest mountain, an area considered to be one of the most well-preserved natural habitats in Europe. The park spans over 403 square kilometers (around 156 square miles) and contains breathtaking landscapes that range from rocky barren peaks to lush forests and glacier lakes to virgin rivers. It is home to numerous threatened flora and fauna species such as the golden eagle, brown bear and chamois. Locals tell stories that the Balkan lynx (an animal long thought to be extinct in the country) is still roaming in the park's territory. A tourist track within Pirin National Park.

Due to its precious natural wonders, Pirin was declared a World Heritage Site by UNESCO in 1983. This status added to its world fame as a tourist destination, a trait valuable to many small and medium-sized businesses in the surrounding area. However, as the adjacent town of Bansko‘s ski resort began hosting winter sports competitions and attracting numerous foreign tourists with its low prices, the sporting complex started to rapidly expand in an unsustainable way. Since 2001, the Bansko resort has expanded way over its allowed territory, funneling droves of tourists to the small town. Hotels, ski tracks and their supporting facilities have already encroached into the nearby national park by over 160 hectares, causing soil erosion, biodiversity loss and pollution to sources of drinking water. In 2010, UNESCO excluded the tourist area, spanning 0.6% of the park, from the World Heritage Site to become its buffer zone and continues to express concerns over the ski resort's expansion. Due to the popularity of the area, Bansko ski resort has a huge accommodation base for a relatively small number of ski tracks and only a single gondola lift line, resulting in traffic jams and long queues of tourists waiting for their lift ticket. The unsustainable development of the ski resort has lead to a rapid increase and then drop in real estate prices. This financial bubble is growing as prospects of even more expansion become reality. In an effort to keep their prices up and sell more properties around Bansko, Ulen (the company that owns ski infrastructure) has spent years lobbying the Bulgarian government to expand concession areas in the national park and to lift restrictions on construction activities in the protected territory by amending its Management Plan (the ten-year framework of what is allowed within the park). Bulgarian mainstream media, mostly owned by powerful oligarchs, downplayed the opposition from environmental NGOs by obscuring the issues of greatest concern by publishing stories which focus on issues that favor the resort such as the overloaded gondola lift line. Government officials backed this version by claiming the plan is being amended only to allow a second gondola line, although this is not actually mentioned in the actual legislation. The environmental minister unwittingly called the government's argument into question when he refused a change to the language which would specify that only one lift is allowed to be built, an amendment proposed by renowned altitude climber Boyan Petrov. Mainstream media also focused on the economic benefits of development and income for the locals. Residents who members work in the concerned companies and their families expressed public support for the resort expansion, regardless of long-term effects on the environment. Despite advice from environmental experts who warned against the development of a large ski area due to climate change and the predicted shortened winter season, the decision makers pressed on.
