As the damage from pollution has become more apparent, more countries are looking to green alternatives to prevent further damage to the Earth.

Solar and wind energy, eco-friendly building materials, and non-toxic products are increasingly being used to preserve the planet. While these green initiatives are taking place around the world, some countries have a long way to go. These particles come from car, truck, bus, and off-road vehicle exhausts and from operations that involve the burning of fossil fuels such as wood, heating oil, or coal. They can also originate from indoor sources such as smoking tobacco, cooking, burning candles, or using fireplaces.

These particles reduce visibility and make the air appear hazy when levels are elevated. Some cities, such as New York , issue a PM2. The AQI ranges from 0 to , with zero representing clean air and being the most hazardous. Values of or below are generally thought of as satisfactory; however, when values are above , air quality is considered unhealthy for certain at-risk groups of people and becomes more unsafe as the value increases.

The cleanest countries in the world , as determined by the Environmental Performance Index EPI , have high air quality, clean water, and strong environmentally-friendly policies and initiatives. These countries include Switzerland , France , and Denmark.

A total of 92 nations were evaluated to determine which had the highest number of PM2. Bangladesh is the most polluted country in the world, with an average PM2. The country's primary environmental pollutants are air and water pollution, groundwater contamination, noise pollution, and solid wastes.

Dhaka City is one of the most polluted cities in the world. In terms of air pollution, Bangladesh's largest source is its brickmaking industry , which employs one million people and creates 23 billion bricks every year. The kilns used in brickmaking burn wood or coal and create mass amounts of smoke and dust.

Due to increased demand for bricks, the brickmaking industry is only expected to grow more, leading to more air pollution.
