Why is phosphorus important to the environment?
Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate), DNA and lipids (fats and oils). Insufficient phosphorus in the soil can result in a decreased crop yield.
What are three negative impacts of phosphate mining?
Most of the impacts are being reflected in the form of changes to local hydrology, water contamination, water consumption, air pollution and human risk .
Why do we need phosphate?
