What are the negative or positive effects auroras have on the environment?

Auroras primarily have positive effects on the environment by indicating the presence of solar activity, which can enhance our understanding of space weather and its impact on Earth's magnetic field. They also contribute to the natural beauty of the night sky, attracting tourism and inspiring scientific research. However, intense solar storms associated with auroras can disrupt satellite communications, navigation systems, and power grids, leading to potential technological and economic challenges. Overall, while auroras themselves are visually stunning and scientifically valuable, the solar activity that generates them can have mixed effects on human infrastructure.
