Unsung bedrock of prosperity (phosphorus)
Modern agriculture would be inconceivable without phosphate fertilisers – and it needs more and more of them. Experts warn of an imminent phosphorus shortage. But not Roland Scholz from the Institute of Environmental Decisions. For him, the main problems are the open phosphorus cycle and non-sustainable resource management. Scholz considers the ecological and social costs of the unsustainable use of the resource to be more problematic than the peak: ‘The environmental damage caused by the extraction and use of phosphorus is still greatly underestimated.’
