Ecosystems are also damaged by (1) the deposition of the acidifying substances – nitrogen oxides, sulphur dioxide and ammonia – which lead to loss of flora and fauna; (2) excess nutrient nitrogen in the form of ammonia and nitrogen oxides can disrupt plant communities, leach into freshwaters leading in each case to a loss of biodiversity (called “eutrophication”); and (3) ground level ozone that results in physical damage and reduced growth of agricultural crops, forests and plants.

76. Recalls that, through water bills, EU citizens are bearing the cost of purification of water and water treatment, and stresses that enacting policies that effectively combine and reconcile water resource protection objectives with cost savings, such as ‘control at source’ approaches, are more efficient and financially preferable; recalls that according to the EEA’s 2015 report on the state of the environment, more than 40 % of rivers and coastal waters are affected by diffuse pollution caused by agriculture, while between 20 % and 25 % are subjected to pollution deriving from point sources such as industrial str ...[+++]uctures, sewage systems and wastewater management networks; highlights the importance of effective implementation of the WFD and the Drinking Water Directive, better coordination as regards their implementation, more coherence when drafting legislation and more proactive measures for saving water resources and substantially increasing water use efficiency across all sectors (industries, households, agriculture, distribution networks); recalls that ensuring sustainable protection of natural areas such as freshwater ecosystems is also key to development and crucial for providing drinking water supplies, and reduces costs for citizens and operators;

Research on marine, (from coastal zones to the deep sea including the sustainability of marine resources), polar , fresh-water, terrestrial and urban ecosystems, including groundwater dependent ecosystems, will improve our understanding of the complex interactions between natural resources and social, economic, and ecological systems, including natural tipping points, and the resilience, or fragility, of human and biological systems.
