Climate change happens when Earth gets sick from people using too many things that make it too warm. It's like putting on too many blankets when you're already warm in bed - the Earth gets too hot. Cars, factories, and machines burn things like coal, oil, and gas, sending gases into the air. These gases act like a big blanket around Earth, trapping heat from the sun, making it hotter and changing the weather. Sometimes it gets too hot, causing droughts, floods, and big storms. The North and South Poles are melting because it's getting warmer, raising the sea level and flooding places where people live. We can help by using less electricity, driving less, and planting trees. It's like giving Earth medicine to feel better and stop getting so hot.
