Final answer:
Fertilizer production is another facet of modern industrial society that contributes to the formation of acid rain, alongside the combustion of fossil fuels.
Step-by-step explanation:
In addition to the combustion of fossil fuels, another facet of modern industrial society that contributes to the formation of acid rain is fertilizer production. The manufacturing of fertilizers involves processes that release various chemicals, including sulfur dioxide and nitrogen oxides, which can combine with atmospheric moisture to produce acidic compounds. When these compounds precipitate, they can lead to the acidification of lakes, rivers, and soil, causing environmental damage to ecosystems and the built environment.
