Explanation:

Environmental Quality: Air pollution is an example. Industrial emissions, vehicle exhausts, and burning of fossil - fuels release pollutants like sulfur dioxide, nitrogen oxides, and particulate matter into the air. These pollutants can cause respiratory problems in humans, harm plants and animals, and contribute to acid rain which damages forests, lakes, and buildings. It also reduces visibility and affects the overall aesthetic and ecological balance of an area.

Human Population and Well - Being: Access to clean water is crucial. As the human population grows, the demand for clean water increases. Lack of clean water can lead to water - borne diseases such as cholera, dysentery, and typhoid. These diseases disproportionately affect vulnerable populations, especially in developing countries. Clean water is also necessary for sanitation, food production (irrigation), and maintaining personal hygiene, all of which are essential for human well - being.

Natural Resources: Forests are a natural resource. They provide timber for construction and paper production. Forests also act as carbon sinks, absorbing carbon dioxide from the atmosphere and helping to mitigate climate change. They are habitats for a vast number of plant and animal species, contributing to biodiversity. Additionally, forests play a role in regulating the water cycle, preventing soil erosion, and providing recreational opportunities for humans.

Answer:

1. For Environmental Quality: Air pollution is caused by industrial emissions, vehicle exhausts, and fossil - fuel burning. It causes health problems in humans, harms ecosystems, and leads to acid rain.
2. For Human Population and Well - Being: Clean water access is vital. Population growth increases demand, and lack of it causes water - borne diseases, especially in vulnerable groups. It's also needed for sanitation, food production, and hygiene.
3. For Natural Resources: Forests provide timber, act as carbon sinks, support biodiversity, regulate the water cycle, prevent soil erosion, and offer recreation.
