So why are we losing biodiversity?
Habitat loss, over-exploitation, climate change, pollution and invasive alien species all contribute to biodiversity loss. But the underlying cause is unsustainable human activities. Our demand for new resources is driving deforestation, changing patterns of land use, and destroying natural habitats all around the globe.
In Europe, the main cause of biodiversity loss is land-use change. Farming and forestry practices have become more intensive, with more chemical additives, fewer spaces between fields, and fewer varieties of crops. This lack of variety means far fewer insects, for example, and consequently fewer birds.
Cities and urban areas have also expanded enormously, leaving less room for nature. And when farmland and urban developments leave no room for nature, the result is a loss of biodiversity.
