The latest data on air quality in major cities around the world, mapped

The American Lung Association State of the Air 2021 report found that despite nationwide efforts in controlling air pollution, more than 40% of Americans – over 135 million people – are still living in areas with unhealthy particulate pollution and ozone levels.

In fact, 9 out of 10 urban dwellers are affected by air pollution. And this isn’t just the case in the United States, and it’s a global problem.

But which cities are the worst, and which are the best for breathing fresh air? To find out, HouseFresh visualized the latest data on air quality in major cities around the world, revealing the most and least polluted cities in nearly every country, as well as in every US state.

Researchers at HouseFresh extracted city-level air quality data from the latest 2020 World Air Quality report by IQAir. Data in hand, the team identified the best and worst cities and towns for clean air across nearly 100 countries and across all 50 US states. Cities and towns were ranked on the average value of PM2.5 concentration in µg/m³ in 2020, and countries without at least five cities were omitted.

Key Findings: 
● Bangladesh takes the top spot as the most polluted country, followed by Pakistan, India, and Mongolia. 
● 49 of the 50 most polluted cities worldwide were in Bangladesh, Pakistan, China, and India. 
● Japanese city Obihiro was Asia’s top city for clean air with a PM2.5 of 5.6µg/m3. 
● Judbury (Australia), Kailua Kona (U.S.A.), and Muonio (Finland) were the cities with the cleanest air around the globe. 
● Susanville in wildfire-ravaged California had the dirtiest air in America with a PM2.5 of 26.2µg/m3.

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North Americ...

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution  created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray ...
