Explanation:

1. Environmental Quality - Air Quality: Air quality is crucial for life on Earth. Polluted air can contain harmful substances like particulate matter, sulfur dioxide, and nitrogen oxides. These pollutants can cause respiratory problems, heart diseases, and even cancer in humans. Additionally, poor air quality can damage plants and ecosystems, affecting biodiversity and the overall balance of nature.
2. Human Population and Well - Being - Access to Healthcare: Access to healthcare is fundamental for human well - being. It ensures that people can receive timely medical treatment for illnesses and injuries. Adequate healthcare also includes preventive measures like vaccinations, which can control the spread of diseases. In areas with limited access to healthcare, mortality rates are often higher, and people may suffer from untreated chronic conditions, reducing their quality of life.
3. Natural Resources - Scarcity: Scarcity of natural resources is a growing concern. As the global population increases, the demand for resources such as water, fossil fuels, and minerals rises. When resources become scarce, it can lead to conflicts between regions or countries. For example, water scarcity can cause disputes over water rights. Moreover, scarcity can drive up prices, affecting economic stability and the ability of people to meet their basic needs.
