Individual actions can help reduce pollution and mitigate climate change. People should reduce waste by reusing and recycling, conserve energy by using it efficiently, and choose environmentally-friendly products. Planting trees also aids in absorbing pollutants from the air. Raising awareness of others on these issues is important as well. Pollution contributes to climate change by increasing greenhouse gases and reducing sunlight reaching Earth, so reducing pollution through individual and collective efforts is key to curbing climate change.
