Pollution is caused primarily by human activities like driving cars instead of walking. This harms both the environment and future generations who will inherit the problems we cause today. Small actions like turning off lights when not in use, lowering the thermostat, replacing incandescent bulbs with LEDs, and fixing dripping faucets can help reduce energy usage and pollution. Planting trees and closing curtains strategically also aids in energy conservation. Working together through individual efforts is key to saving the planet.
