For two and a half years, environmentalists have waged a war with the Polish authorities for Białowieża Forest, a UNESCO World Heritage Site and one of Europe's last and largest remaining patches of Europe's original primeval forest.
In April 2018, the European Court of Justice, the EU's highest court, ruled that Poland violated EU laws by logging in the forest, imposing fines of a minimum of 4.3 million euros (five million US dollars), potentially rising
to 100,000 euros a day, if the felling doesn't stop.
