In Europe, phosphorus is being treated in an unsustainable way. Through fertilizers, sewage and animal manure, large amounts of phosphorus and other nutrients end up in ground water and water bodies.
This is a direct threat for our aquatic ecosystems due to the process of eutrophication: increased levels of nutrients resulting in oxygen depletion. The impact on biodiversity is critical, since certain fish and other aquatic animal populations do not survive or invasive new species are introduced.
