Answer:
While fertilizers can be beneficial for plants and help them grow, they can also have negative effects on the environment. One of the main concerns with the use of fertilizers is that they can leach into nearby water sources, such as rivers and streams, and cause an excess of nutrients in the water. This can lead to the growth of harmful algae and other aquatic plants, which can deplete the water of oxygen and kill fish and other aquatic life. Additionally, fertilizers can also release harmful pollutants into the air, such as nitrogen oxides, which can contribute to air pollution and damage the ozone layer. Therefore, it is important to use fertilizers responsibly and follow the instructions on the packaging to avoid any negative effects on the environment.
