Pollution Problems

Global air pollution is on the rise despite efforts to stop it, according to a new World Health Organization (WHO) report. More than 80% of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed WHO limits. While all people around the globe are impacted by poor air quality, some are more affected than others. “Air pollution is a major cause of disease,” said WHO official Flavia Bustreo. “When dirty air blankets our cities the most vulnerable urban populations—the youngest, oldest and poorest—are the most impacted.”

While air pollution in countries like Delhi, India (pictured above), and Mexico City, Mexico, is particularly serious, the problem extends to areas around the world. Ninety-eight of 100 cities in low- and middle-income countries do not meet air quality standards. To help clear the air, environmental experts say that countries should develop clean energy sources, like solar panels, rather than coal-fired power plants.
