Earth is the only planet with a male solar system. It’s all thanks to us having a great atmosphere and an ideal environment. However, in recent years, with the strong development of the society, the environment is seriously damaged. The air and water sources are both heavily polluted. Natural disasters take place with a greater frequency and are more severe. Large-scale wildfires occur in many countries. Is this Mother Nature wanting to send a wake-up call to man. If humans are still indifferent, we will kill ourselves. So what can we do to protect the environment? Uncle Ho used to teach “When you are young, do small things, depending on your strength”. Let’s start from the smallest and simplest things such as not littering, not littering ponds, lakes, rivers, streams, and actively planting trees around schools and houses. Trees will contribute to converting CO₂ in the air into O₂ gas. The State has also taken tough measures to punish individuals and organizations that have acts of causing environmental pollution. Organizing projects to plant trees, cause forests, to green barren hills. As a student, I always try to protect the environment, and at the same time propagate for those around me to know and implement.
