Is acid rain getting better or worse?

Acid rain has generally improved in many regions, particularly in North America and Europe, due to stricter environmental regulations and reductions in sulfur dioxide and nitrogen oxides emissions. However, in some developing countries and areas with high industrial activity, acid rain remains a significant issue. Ongoing monitoring and efforts are necessary to address both existing and emerging sources of pollutants contributing to acid rain. Overall, while progress has been made, continued vigilance is essential to maintain and further improve air quality.
