The causes and problems of air pollution today

A polluted environment is a polluted society - one we created and one only we can renew. Pollution is defined as the introduction of harmful substances or products into the environment, which are typically foreign substances, particularly a contaminant or toxin, that produce some kind of a negative or harmful impact on the environment or living beings.

The new estimates are based on the latest WHO mortality data from as well as evidence of health risks from air pollution exposures.

This incorporated satellite data, ground-level monitoring measurements and data on pollution emissions from key sources, as well as modelling of how pollution drifts in the air.

The new estimate is explained by better information about pollution exposures among the estimated 2. In the case of outdoor air pollution, WHO estimates there were 3. Many people are exposed to both indoor and outdoor air pollution.

Due to this overlap, mortality attributed to the two sources cannot simply be added together, hence the total estimate of around 7 million deaths in This involves the development of a WHO-hosted global platform on air quality and health to generate better data on air pollution-related diseases and strengthened support to countries and cities through guidance, information and evidence about health gains from key interventions.

Later this year, WHO will release indoor air quality guidelines on household fuel combustion, as well as country data on outdoor and indoor air pollution exposures and related mortality, plus an update of air quality measurements in cities from all regions of the world.

The good news: Air has gotten cleaner in recent years.

The Cause and Effects of Air Pollution

Now the bad: More than half of people in the U.S. still breathe air dirty enough to cause health problems, according to the American Lung. What Causes Air Pollution? “Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC.

All these sources are constantly contributing in air pollution turning it into a major problem today. Deforestation – Trees and forests help in purifying the air by taking in carbon dioxide.

The cutting of forests leads to presence of carbon dioxide in excess amount and air pollution. Allergens and pollutants in the air—like dust, outdoor air pollution, and strong odors like perfume—may contribute to coughing, irritate your nose, and .

Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications. Like humans, animals can suffer from a number of health problems due to air pollution, including birth defects, reproductive failure, and diseases.
