Introduction to Carbon Sequestration 🌱
- Definition: Capturing and storing carbon.
- Why it's important: A scientific method to combat global concerns like climate change.
- Natural methods
- Geological processes.
- Biological processes
- Photosynthesis (plants turning CO₂ into sugar).
- Growing vegetation & wood.
- Aquatic organisms building shells.
- Settling of undigested particles from the ocean surface to the deep sea.
Plant More Trees, Save the Planet! 🌲🌳
- Afforestation
- Definition: Planting trees where none existed.
- Real-World Commitments
- Canada - 2 billion trees.
- The Bahamas - 1 million trees.
- Did you know? The European Union has been paying farmers to plant trees since 1990!
- Cool Project: The Great Green Wall – 19 North African countries teaming up to plant trees and stop the desert from spreading!
- Reforestation
- Definition: Replanting forests that were cut down or depleted.
- How it's done: Tree planters sow seedlings after an area has been cleared.
- Beware of monocultures: Planting only one type of tree can be risky due to diseases and less diversity.
Peaty Facts! 🌾
- What's Peat?: Partially decayed organic matter from wet, squishy places like bogs.
- Uses: Fuel, heating, fertilizer, and gardening.
- Peat Locations: Wet, waterlogged soils in temperate, boreal zones, and some tropical ecosystems.
- Why Peat's Important: They're like Earth's carbon piggy bank! The world’s largest carbon sink.
- Peat Fires: 🔥 Burn long and hard to put out!
- Saving Peatlands: The Global Peatlands Initiative works to protect and restore peatlands by managing water levels, stopping drainage, and planting native species.
