What answer gives both a positive impact and a negative impact that are associated with the effects of nitrogen and phosphorus-enhanced fertilizers?

Nitrogen and phosphorus-enhanced fertilizers can significantly boost agricultural productivity by improving crop yields and ensuring food security, which is a positive impact. However, their overuse can lead to negative environmental consequences, such as water pollution from runoff, causing eutrophication in aquatic ecosystems. This dual effect highlights the need for balanced fertilizer application to optimize benefits while minimizing harm.
