On March 31 individuals, businesses and cities around the world will take part in the annual Earth Hour celebrations, designed to raise awareness of climate change and environmental issues.  In honor of Earth Hour, Relaxnews has compiled a list of some of the apps that measure, or provide information on, one of the most potentially harmful environmental problems on our health -- air quality.

Prolonged exposure to outdoor air pollution can have detrimental effects on personal well-being as well as the surrounding environment. However, people can reduce their level of exposure to air pollution by taking simple steps, such as walking or cycling on side roads, not main roads, and being aware of the air quality where they live. One of the easiest and quickest ways to find out about the air quality where you live is by consulting the apps shown below:
