Old forest is being savagely clear-cut and replaced by monoculture plantations to the detriment of animals, insects, birds and the entire rich ecology of the ancient woodlands. The new plantations have introduced new diseases and encouraged pests that further damage the old-growth trees - leading to even more clear-cutting to prevent the spread of the new blights.
Near to where my family have a cottage, a forest that surrounded the visible remains of a bronze-age settlement was brutally clear-cut using the usual enormous machinery that completely churns the land and scars it irrevocably. The forest itself was probably five or six-hundred years old, and it was felled by these monstrous machines in a morning, leaving just horrifically bare soil and the cratered disfigurement of industrial forestry. No-one cares.
