human impact on ecosystems examples

📚 Quick Study Guide

• 🏭 Industrialization: Increased pollution and habitat destruction.
• 🌱 Deforestation: Loss of biodiversity and increased carbon emissions.
• 🚗 Transportation: Air pollution and greenhouse gas emissions.
• 🌾 Agriculture: Fertilizer runoff and soil degradation.
• 🗑️ Waste Disposal: Landfill overflow and plastic pollution.
• 🌡️ Climate Change: Rising temperatures and extreme weather events, largely due to increased greenhouse gasses like carbon dioxide ($CO_2$) and methane ($CH_4$).
• 🐟 Overfishing: Depletion of fish stocks and disruption of marine ecosystems.
