Environmental quality refers to the condition of the natural environment and how it affects living organisms. It encompasses various factors, including air and water quality, soil health, and biodiversity. High environmental quality means clean air, safe drinking water, and healthy ecosystems, which are essential for human health and well-being. Several indicators are used to measure environmental quality, such as levels of pollutants, availability of natural resources, and the presence of endangered species. Governments and organizations often monitor these indicators to ensure sustainable development and protect the environment for future generations.
