Plants need sunlight to grow and stay healthy. Through a process called photosynthesis, they turn light into energy. They take in carbon dioxide from the air and release oxygen for us to breathe. This amazing cycle happens in their green leaves every day. Without plants, life on Earth would be very difficult. We must protect plants to keep our planet clean and healthy.
