Which region is the least affected by acid rain?

Regions with low industrial activity, such as remote rural areas or regions with a high prevalence of natural buffers like limestone, are typically the least affected by acid rain. For example, parts of Canada and Scandinavia, where the natural environment can neutralize acidic compounds, often experience lower levels of acid rain. Additionally, areas with fewer emissions of sulfur dioxide and nitrogen oxides, which are the primary contributors to acid rain, tend to be less impacted.
