Global warming is an environmental phenomenon where the Earth's average temperature rises due to the trapping of heat by greenhouse gases. While it affects the Earth and human health, the primary damage is to the global environment.

Air pollution, especially particulates and greenhouse gases, affects temperature patterns. Urban areas with high pollution show greater warming trends, particularly noticeable at night and in winter due to the urban heat island effect and pollution trapping heat. This is an environmental effect of air pollution.

Natural gas is a versatile, clean-burning, and efficient fuel that is used in a wide variety of applications. It can be used in the form of compressed natural gas (CNG) or liquefied natural gas (LNG) to fuel cars and trucks.  Natural gas as a vehicle fuel is much cheaper and environmentally cleaner than petroleum products.

LPG or Liquefied Petroleum Gas is basically used in households as a fuel for cooking.

Kanpur is historically known for its high levels of air pollution due to its dense concentration of leather and textile factories, which emit significant amounts of smoke and dust.

Primary pollutants are emitted directly from a source into the atmosphere, such as carbon monoxide from car exhausts. Secondary pollutants are formed in the atmosphere through chemical reactions between primary pollutants.

Air pollutants are generally classified based on their physical state into two types: gaseous pollutants (like CO2, SO2) and particulate matter (like dust, smoke, mist).

Carbon monoxide is a product of incomplete combustion of carbon-containing fuels, such as gasoline, wood, and coal, which are common in motor vehicles and waste disposal.

SPM stands for Suspended Particulate Matter, which refers to tiny solid or liquid particles suspended in the air.

Sandbags are commonly used in flood control and to reinforce river banks because they are heavy, durable, and effective at preventing erosion and water seepage.
