Europe’s nature is filled with forests, mountains, vast plains, long rivers, deep blue seas and refreshing lakes. But it also is under threat. Unsustainable farming and forestry practices, pollution, climate change and invasive species are stressing and destabilising all natural systems in Europe. The result is a biodiversity crisis. The EU is taking steps to protect and restore nature.

Pollution, over-use and climate change threaten Europe's lakes, rivers and groundwater

Agriculture is the most significant pressure impacting both surface and groundwaters, according to the EEA report ‘Europe's state of water 2024: the need for improved water resilience’. This results from water use and pollution from the intensive use of nutrients and pesticides.

The EEA’s report shows that, despite some progress, Europe’s waters and aquatic ecosystems are still severely impacted by chemicals, predominantly by air pollution from coal-powered energy generation and diffuse pollution by nutrients and pesticides from agriculture. Habitat degradation is also widespread. Adding to the challenge to protect aquatic ecosystems is climate change, which is disrupting weather patterns and further increasing pressures on water resources and management.

Toxic substances found in shellfish

In the marine environment, hazardous substances accumulate in fish and shellfish, which are a food source for other marine animals and humans alike. Between 2010 and 2021, nine hazardous substances were monitored in marine organisims, all exceeding safe limit values.

High levels were observed for benzo[a]pyrene, DDE (a breakdown product of DDT), and polychlorinated biphenyl (PCB). Few time trends show more decreasing concentrations (improvements) than increasing ones, except for mercury.

The contaminants are toxic for marine biota, and consuming contaminated seafoods may generate detrimental effects on human health, such as structural damage or failure of organs and increased cancer risk. Reducing concentrations of these substances helps achieve the 'good environmental status under the Marine Strategy Framework Directive and the Zero Pollution Action Plan targets.

Birds: an indicator of environmental health

Birds are sensitive to environmental pressures and their populations can reflect changes in the health of the environment.

Long-term trends show that between 1990 and 2021, the index of 168 common birds decreased by 12% in the EU. The decline was much stronger in common farmland birds, at 36%, while the common forest bird index decreased by 5%.

At present, it seems unlikely that the decline in populations of common birds can be reversed by 2030.
