Which 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 lead to positive impacts, such as increased crop yields and improved food production, which help meet the demands of a growing population. However, these fertilizers can also have negative consequences, including water pollution through runoff, which can cause algal blooms and harm aquatic ecosystems. This duality highlights the need for balanced agricultural practices that maximize benefits while minimizing environmental harm.
