Air quality is getting better as a result of anti-pollution regulation, and we are all healthier as a result. But air pollution remains a deadly killer, in unexpected ways that go way beyond lung diseases such as asthma and lung cancer. A wide range of new research summarized in this study https://www.sciencenews.org/article/list-diseases-linked-air-pollution-growing documents that air pollution is a major cause of cancer, obesity, and cognitive decline. The biggest culprit are fine particles that are emitted from diesel and gas engines, as well as other sources. Getting diesel and gas engines off our roads will allow us to live healthier and longer lives. Now that electric vehicles are providing a good alternative to gas and diesel, doesn’t it make sense for us to make the switch?
