It will also help avoid 2.78 million asthma attacks and 13.4 million lost workdays. In short, its value is equivalent to $1.2 trillion in public health benefits < p > this study assumes that all new passenger vehicles sold in the United States by 2035 are electric vehicles, and all heavy vehicles sold by 2040 are also electric vehicles. More importantly, these vehicles need to be supported by a grid powered by non fossil fuels < p > but in such a short time, it is almost impossible to replace the vast majority of the country's about 280 million cars and trucks with electric vehicles. Despite the growing popularity of electric vehicles, electric vehicles accounted for less than 3% of new cars sold in the United States in 2021 < p > nevertheless, health advocates say we must strive to create a safer environment. Pediatrician Afif El Hasan, a volunteer with the American Lung Association, said: "I can advise patients to spend less time outdoors to limit their breathing of polluted air, but I am not always frustrated that I can ensure that they have clean and healthy air to breathe. Growing and playing in a safe place should be the right of every child, which should never be the focus of debate." < p > according to the American Lung Association, more than 40% of Americans live in places with unhealthy air pollution levels. Inhaling this polluted air causes many people to suffer from cancer, heart disease, stroke and lung diseases. It will also affect the development of children's lungs and affect their lives. At the same time, people of color are more negatively affected by air pollution. They are three times more likely to breathe serious air pollution than white Americans < p > in its latest report, the American Lung Association studied the impact of phasing out fossil fuels in the transportation and power industries on limiting key pollutants, including reducing soot, smoke forming nitrogen oxides and volatile organic compounds, and sulfur dioxide from automobile exhaust pipes and chimneys < p > the authors also studied another less concerned source of pollution, non exhaust emissions. This includes road and vehicle wear particles into the air, such as tires or brake pads. The persistence of this type of pollution suggests that better public transport and more walkable cities can help reduce dependence on driving, which is also important to ensure a healthier future The report also points out that reducing greenhouse gas emissions leading to climate warming is also good for human health. Climate warming will accelerate the chemical reaction that produces smoke and aggravate the pollution caused by wildfires, thus affecting air quality. An industry commissioned report recently released by the German Aerospace Center shows that electric bicycles, scooters and other light electric vehicles can also significantly reduce greenhouse gas pollution when they replace cars < p > in the United States, President Joe Biden has set a goal that by 2030, half of all new cars sold in the United States will be electric or hybrid vehicles. Earlier this month, the EPA proposed new regulations specifically aimed at reducing truck pollution. The Biden administration's climate goal also includes decarbonizing the power sector by 2035 < p > the report of the American Lung Association emphasizes that phasing out fossil fuels in the power grid is crucial to building environmentally friendly transportation. But so far, many efforts to curb pollution have not achieved substantive results, and pollution continues to cause damage to people's health. (small) < / P > < p >
