#5 Population Blast In Urban Areas Causing Death And Ill Health
Cities today are getting over populated. Approximately 4 billion people are now residing in various urban areas in different parts of the globe.
Now this skyrocketing population apart from exhausting the natural resources is spreading viruses and disease at a fast rate. That is another reason for concern. Inadequate sanitation will only add to the negative health effects.
According to the World Health Organization, outdoor air pollution is estimated to have caused 3.7 million premature deaths worldwide in 2012. This will only increase as urban populations rise and pollution worsens.
