Not to be a drama queen about it, but the organization Natural England have published findings of their first audit of all of England's lost and declining native species.
The report is called Lost Life: England's Lost and Threatened Species and can be found following the link. Apparently,
"habitat loss, inappropriate management, environmental pollution and pressure from non-native species have all played a part in the erosion of England’s biodiversity."
Is this scenario any different in other countries? I doubt it......
