What are Greenhouse Gases? | Science Lesson

Greenhouse gases help keep Earth warm, but too much of them causes climate change. 🌡️🚨 🔹 Where extra greenhouse gases come from: 🏭 Burning fossil fuels – Cars, factories, and power plants release CO₂. 🚗⚡ 🌳 Deforestation – Fewer trees = more CO₂ in the air. 🪓🔥 🐄 Agriculture – Cows and farms produce methane (CH₄), a powerful heat-trapping gas. 🌾🥩 🗑️ Landfills – Rotting waste releases methane into the atmosphere. ♻️ 🔹 How we can help: ☀️ Use renewable energy – Solar, wind, and hydro power instead of fossil fuels. 💨🔋 🌳 Plant trees & protect forests – Trees absorb CO₂ and clean the air. 🌲🌎 🚲 Choose eco-friendly travel – Walking, biking, or public transit reduces emissions. 🚌🚴 🍽️ Reduce food waste & compost – Less waste = less methane. ♻️🗑️ 🔥 Climate change is happening, but we can slow it down! Small actions make a big difference. What can you do today? 🌿💡 🔬 This lesson follows the Ontario Grade 7 Science curriculum but can be used in various science programs.
