Fertilizers
Fertilizers have played an essential role in feeding a growing global population. It’s estimated that just under half of the people alive today are dependent on synthetic fertilizers.
They can bring environmental benefits too: fertilizers can increase crop yields. By increasing crop yields we can reduce the amount of land we use for agriculture. But they also create environmental pollution. Many countries overapply fertilizers, leading to the runoff of nutrients into water systems and ecosystems.
