An organism that eats other organisms for energy.

The process by which certain gases trap heat in the atmosphere.

Burning fossil fuels, factories, and cars release harmful pollutants into the air.

The AQHI is grouped into five categories, from low to very high, based on the level of pollution.

Breathing polluted air can cause respiratory problems, cardiovascular diseases, and other health issues.

A greenhouse gas released from burning fossil fuels, contributing to climate change.

A pollutant released by burning fossil fuels that can irritate the lungs and contribute to acid rain.

Pollutants released by burning fossil fuels, contributing to smog and acid rain.

The AQHI informs people about the air quality and potential health risks, helping them make informed decisions about outdoor activities.

The AQHI categorizes air quality based on health risks, from low risk to very high risk.

Indicates a higher level of air pollution, posing greater health risks, especially for vulnerable groups.

When the AQHI is high, it's recommended to reduce outdoor activities and time spent outside.

Individuals with health conditions, such as heart or respiratory illnesses, should be particularly cautious during periods of high air pollution.

Individuals can minimize their exposure to air pollution by staying indoors, avoiding strenuous activities outdoors, and using air purifiers.

Using buses, trains, and subways can reduce car traffic and air pollution.
