The Nitrogen in Europe project adopts a multidisciplinary approach to examining and tackling the main problems of excess nitrogen. It identifies nine main problems associated with excessive nitrogen use: aquatic, coastal and terrestrial eutrophication, acidification, climate change, photochemical smog, urban air quality, particles, and stratospheric ozone depletion. The project has recently drafted a declaration on nitrogen and the food chain which you can read here.

This synthesis of academic and non-academic literature highlights what is and is not known about public attitudes to environmental change. It reviews attitudes and responses to: climate change; specific climate change impacts (i.e. flooding, heat stress and rising sea levels); changes in ecosystems, landscapes and species; energy technologies and infrastructure (including renewables, fossil fuels and nuclear energy); and different campaigns and engagement activities and their successes and different theories associated with environmental change attitudes.
