Fertilizer run-off from industrial agriculture is choking the planet’s oceans, rivers and lakes. Nitrogen and phosphorus pollution feed explosive algal blooms that suck the oxygen from the water as they grow. These algal blooms result in dead zones that pose an ever-increasing threat to marine life as their habitats disappear. The publication ›Suffocating Waters‹ aims to draw the reader's attention to this issue through tailored infographics and map materials. The specially developed imagery shows the processes on a narrative level and supports the text. The maps provide quantitative information and are intended to encourage readers to conduct their investigations into the correlations between nitrate levels and declining oxygen levels.
