According to The Guardian, the Citarum River in Indonesia is so polluted that before you see it, you will smell it.
The Yangtze alone dumps up to an estimated 1.5 million metric tons of plastic waste into the Yellow Sea. Better waste collection and management practices in the most polluted regions would help stem the tide, Schmidt says, but raising public awareness is also crucial.
Of the 25 least polluted cities in the world with the best air quality, Nordic countries (Finland, Sweden, Norway, Iceland, Estonia) dominated the rankings with some of the cleanest air in the world in 2022.
But China's contribution to the global plastic crisis does not end there. China is also by far the largest source of mismanaged plastic waste, and is the biggest offender of ocean plastic pollution. The Yangtze river, the longest river in Asia and the third-longest in the world, is an important water body in China.
World's top 10 ocean plastic contributors
Based on a study by Science Advances in 2021, the Philippines is the leading country on the list of top 10 ocean plastic contributors – generating an estimated 356,371 MT of plastic waste in our ocean.
Nevertheless, in Ganga, an unknown factor acts on the organic matter and bacteria and kills them. Ganga's self-purifying property leads to retaining 25 times more oxygen levels than any other river in the world.

As you'd expect of a country with a population of 1.4 billion, China produces the most municipal solid waste (over 15%). However, considering in terms of population, the US generates the most waste per person. The United States makes up around 5% of the world's population but produces 12% of the solid waste.
How bad is the air pollution in Australia? Australia air quality is generally among some of the cleanest in the world, although the country is vulnerable to short-term extreme pollution spikes which occur due to bushfires and dust storms.
The major contributors to the air pollution in Dubai are vehicular emissions, industrial activities, construction sites, and dust storms. The high levels of pollution can have adverse effects on the health of the residents and tourists, causing respiratory problems, heart disease, and other health issues.
