*Global Warming* Global warming means the slow increase in the average temperature of Earth’s atmosphere. It is one of the biggest problems the world faces today. The main reason for global warming is pollution. Factories, cars, and power plants release a lot of carbon dioxide and other gases into the air. Cutting down trees also makes the problem worse because trees clean the air. Due to these gases, heat gets trapped around the Earth, just like in a greenhouse. Because of global warming, we are seeing many changes. Glaciers are melting fast, sea levels are rising, and floods are becoming more common. Summers are getting hotter and winters are getting colder. Crops are failing, and many animals are losing their homes. The effects are already visible in Pakistan too. Heatwaves, heavy rains, and smog have increased in the last few years. We can still fix this if we act now. We should plant more trees, use less electricity, and switch to solar and wind energy. People should use public transport and avoid wasting water. Big industries and governments also need to make strict rules to control pollution. If we don’t take action today, our children will face a much harder world tomorrow. Saving the Earth is saving ourselves.
