Examples of air pollution effects on plants, animals, and humans.

📚 Quick Study Guide

• 💨 Air pollution includes gases (like ozone and nitrogen oxides) and particulate matter.
• 🌱 Plants suffer from reduced photosynthesis and stunted growth due to pollutants blocking sunlight and damaging leaves.
• 🐾 Animals experience respiratory problems, reproductive issues, and bioaccumulation of toxins.
• 🧑‍⚕️ Humans face respiratory illnesses, cardiovascular problems, and increased cancer risk from prolonged exposure.
• 🏭 Major sources of air pollution include industrial emissions, vehicle exhaust, and agricultural activities.
• 🌧️ Acid rain, formed by pollutants like sulfur dioxide ($SO_2$) and nitrogen oxides ($NO_x$), damages ecosystems.
• 🌡️ Air pollution contributes to climate change by trapping heat in the atmosphere.
