Grade 8 Earth and Space Science human impacts quiz

📚 Quick Study Guide

• 🏭 Pollution: Release of harmful substances into the environment (air, water, land).
• 🌳 Deforestation: Clearing forests for other uses, reducing biodiversity and increasing carbon dioxide.
• 🚜 Agriculture: Intensive farming practices can lead to soil erosion, water pollution, and habitat loss.
• 🌡️ Climate Change: Burning fossil fuels increases greenhouse gases, leading to rising temperatures and changing weather patterns.
• 🌊 Overfishing: Removing fish from the ocean faster than they can reproduce, disrupting marine ecosystems.
• ⛏️ Mining: Extraction of minerals and resources can cause habitat destruction and pollution.
• 🗑️ Waste Disposal: Improper disposal of waste can contaminate soil and water, and release harmful gases.
• 🐾 Habitat Destruction: Destroying natural habitats threatens plant and animal species.
