For instance, according to a report by the World Health Organization (WHO), approximately 90% of the world's population lives in areas where the air quality exceeds safe limits set by international standards.

Secondly, protecting the environment is crucial for several reasons. Firstly, it ensures the sustainability of natural resources, which are essential for human survival and economic development.

To address these issues effectively, several measures need to be implemented. Governments should enact stricter environmental laws and regulations to reduce industrial pollution and promote the use of clean energy sources. Additionally, public awareness campaigns can educate individuals about the importance of recycling and reducing waste. Furthermore, supporting green technologies and sustainable practices can help create new economic opportunities while protecting the environment.
这一段提出了一些具体的解决措施，包括政府立法、公众教育和支持绿色技术等。

In conclusion, environmental protection is not only a moral obligation but also an urgent necessity for the well-being of present and future generations. By recognizing the severity of environmental problems, understanding their impact, and taking proactive steps to address them, we can work towards a healthier and more sustainable world.
