Europe’s forests threatened by biodiversity collapse, warn campaigners

Logging in Poland's Vistula lagoon described by experts as part of a 'war on nature' across the continent's ancient forests

A logging operation at Poland's spectacular 55-mile-long Vistula lagoon is casting a "dark omen" of deforestation and biodiversity collapse across Europe's forests, campaigners say.

Tree felling around the Natura 2000 site is aimed at clearing a path to the Baltic Sea for use by Poland's navy, to the alarm of Russia. But they are just one front in what some academics describe as a war on nature.
