Economic Effects of Air Pollution. Park visitation is largely dependent on protection of natural and scenic resources that draw visitors to national parks in the first place. Economics provides a means to compare the potential benefits of a policy with its potential costs. Ecosystems in national park areas provide goods and services, such as air purification, nutrient cycling, and recreational experiences, that are vital to human health and livelihood. These goods and services are known as ecosystem services. Air pollutants including ground-level ozone, nitrogen oxides, ammonia, and sulphur dioxide can all have negative impacts on ecosystem services. Recognizing ecosystems as natural assets with economic and social value can help promote conservation and more responsible decision-making.
