Why is the Taj Mahal changing color

Rainwater is vital for life, but what happens when it turns corrosive? Atmospheric changes are fundamentally altering the chemical makeup of our rainfall, leading to widespread environmental damage. Acid rain occurs when oxides of sulfur and nitrogen from industrial sources mix with moisture to form harmful acids. This corrosive cycle impacts everything from human health and plant life to historical monuments and aquatic ecosystems. Rainwater is classified as acid rain when its pH value falls to 5.6 or below. Sulfuric and nitric acids are responsible for the vast majority of acidification. Aquatic food chains are collapsing in acidified lakes across regions like Scandinavia. Historical structures made of marble, such as the Taj Mahal, are suffering physical disfigurement. Transitioning to wind, solar, and nuclear energy is essential to prevent further damage. Understanding the chemical drivers behind this issue is the first step toward effective remediation. By shifting away from coal and treating affected soil with lime, we can begin to repair the damage to our environment. If our energy choices directly impact the integrity of historical monuments, should we prioritize a faster transition to renewable fuels?
