Jim Zhang: environmental health is a rewarding career to pursue!
Air pollution has been recognized as a major cause of death and disease globally. It poses health effects that lay burden on hospital admissions, emergency visits and increase the risk of premature deaths. According to the statistics of World Health Organization (WHO), an estimated 4.2 million premature deaths globally are associated with air pollution, which accounts for deaths and disease from lung cancer, stroke, ischaemic heart disease, acute respiratory infection and chronic obstructive pulmonary disease (1). The situation is indeed alarming and has to be dealt with by our joint efforts and unceasing actions.
