In Poland, environmentalists are celebrating after Europe’s highest court ordered an immediate halt to large-scale logging in one of the continent’s last pristine forests. Tuesday’s ruling by the European Union Court of Justice found Poland violated EU laws by allowing as many as 100,000 ancient trees to be logged in the Bialowieza Forest. Following the ruling, Greenpeace and other forest protectors have demanded Poland’s government drop charges against 300 activists arrested during protests against the illegal logging.
