It is claimed in the passage that the depletion of global fish stocks ----.

The loss of global biodiversity is occurring at an
alarming rate. Since the 1970s, the area of tropical
forests destroyed worldwide exceeds the land mass
of the European Union. Animal and plant species are
disappearing. Overfishing has depleted stocks
around the world. Poor farming practices have
depleted soils while allowing the invasion of harmful
species. Destruction of wetlands has left low-lying
areas extremely vulnerable to storms and natural
disasters. Especially in Europe, ecosystems have
suffered more human-induced damage than those on
any other continent. Only about 3 per cent of
Europe's forests can be classified as undisturbed by
humans, and the continent has lost more than half of
its wetlands. The spread of urbanization and the
over-exploitation of resources is having an enormous
impact on biodiversity.
