People living in urban areas have more scope for generating waste than those living in rural areas. They consume more than the villagers. They use more packaged items, including food items, thus generating more waste of packing materials.
Why are cities more polluted?
The sources of air pollution are intrinsically linked to how we live in cities. While many people see cars and transport as the most obvious causes of air pollution, nearly 70\% of particulate matter is related to the built environment such as heating of buildings, construction and traffic related to it.
Why are urban areas more polluted than rural ones?
Urban pollution may come from natural sources, but the most detrimental are those emissions related to human activities. The anthropogenic sources of pollution, such as factories, industries, transportation, and so on, are typically exacerbated in cities due to the local concentration of humans and human activities.
What is causing air pollution in India?
One major source of air pollution is from burning wood, cow dung, and other solid fuels for cooking food in low-income households due to lack of access to clean cookstoves. Over a decade ago, in 2010, more than 150 million solid fuel burning cook stoves were the most lethal source of PM2. 5-related emissions in India.
What city has the most garbage?
Among the world’s mega-metropolitans, Mexico City disgorges the most junk after the New York swathes: 12m tonnes per year. Mexico City throws up 1.8 kilos of garbage per person. This translates to 16.5 million kilograms of waste per day in the nation’s capital.
Why do cities have worse air quality?
Another major contributor to air pollution in cities is the burning of domestic fuels and natural gas. This includes many different fuels, such as coal, gas, and wood. Fuel that is used for both cooking and heating, such as natural gas, can create many different forms of air pollution.
Why are cities bad for the environment?

What are the main causes of pollution in cities?
Increasing population is the first drastic cause for pollution in cities. Increased use of vehicles for transporting and the toxic fuel produced by vehicles. Poor drainage, unavailabilty of sanitation facilities, stagnated waters, uneven roads lead to health pollution.
Is Delhi’s pollution declining?
In the recent study held by WHO in 2018, it came to light that while Delhi has seen a marginal decline in level of pollution, the other cities in India have joined the other global cities with the highest levels of particulate matter (PM).
