The main causes of biodiversity loss are changes in natural habitats. These are mostly due to: intensive agricultural production systems and land abandonment; construction and transport (fragmentation); overexploitation of forests, oceans, rivers, lakes and soils; invasion of alien species; pollution; and — increasingly — climate change. For any policy to be effective in maintaining and restoring biodiversity in Europe, it must address these threats.
Habitat loss — a major concern
70 % of species are threatened by the loss of their habitat (IUCN). Farmland birds declined by 20–25 % between 1990 and 2007 (Eurostat, 2010).
Overexploitation — more sustainability needed
30 % of species are threatened by overexploitation (IUCN). For instance: 88 % of stocks are being fished beyond Maximum Sustainable Yields (ICES, 2008) and 46 % outside safe biological limits, which means that stocks may not be replenished (EEA, 2010).
Europe's protected areas play a key role in protecting biodiversity. But they are also a critical component of the continent’s economy, contributing over EUR 15 billion a year in jobs, food, and ...
