[4] [5] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
This is the market for shipping pollution. The optimal quantity and the optimal tax per unit of pollution can be found at the intersection of MAC and MD. As the quantity of pollution decreases (emissions), the cost to decrease each marginal unit of pollution increases. Since 2009, UPS deliveries have increased by 65%. [49]
The U.S. also saw an uptick in air pollution, climbing from a nationwide average of 8.9 µg/m3 in 2022 to 9.1 in 2023, with the southward-drifting smoke from Canada’s wildfires partly to blame.
Vulnerability to toxic pollution in these communities is compounded, Zhang said, by other disadvantages, including inadequate access to health care or healthy foods. Louisville's 2017 Health ...
Mobile source air pollution includes any air pollution emitted by motor vehicles, airplanes, locomotives, and other engines and equipment that can be moved from one location to another. Many of these pollutants contribute to environmental degradation and have negative effects on human health.
Anxious airline flyers may well remember 2024 as the year their worst fears about the safety of air travel felt confirmed, as a series of unprecedented, and in some cases fatal, airplane incidents ...
