Nowadays, more and more people are paying attention to environmental pollution. It is obvious that this issue poses a great threat to our health and the planet's ecosystem.
分析原因或危害：
The main causes of environmental pollution include industrial emissions, excessive use of plastic products, and inadequate waste management systems. These factors contribute to the increase in air, water, and soil pollution, which in turn affect the health of living organisms and the balance of ecosystems.
提出解决方法或措施：
To address environmental pollution, measures should be taken to reduce industrial emissions by promoting cleaner production techniques and stricter regulations. Additionally, public awareness campaigns should be launched to encourage the reduction of plastic waste and the proper disposal of household garbage. Governments and organizations should also invest in research and development of sustainable energy sources to lessen our reliance on fossil fuels.
