Smog is hitting the UK hard: cities across the country are currently covered in a blanket of dirty air thanks to what meteorologists are calling a perfect storm for air pollution. The UKs environmental department recently reported that the air couldnt be much dirtier in London and southeast England, essentially because dirt from the country as well as dirt from the Sahara Desert isnt being blown away. Local emissions mixed with dust particles from the Sahara are staying in Englands air because light winds are not powerful enough to disperse them. According to a poll conducted by Asthma UK, 84 percent of people with asthma have had flareups due to air pollution.
