What are the leading causes of death globally?
It depends on what you consider a death.
The World Health Organization (WHO) provides the following information at https://www.who.int/news-room/fact-sheets/detail/the-top-10-causes-of-death
"Of the 56.9 million deaths worldwide, more than half (54%) were due to the top 10 causes."
The article includes a chart of the WHO's list of top ten causes of death. Six are non-communicable diseases, like ischaemic heart disease, stroke, and chronic obstructive pulmonary disease. Three are communicable diseases: lower respiratory infection, diarrhoeal diseases & tuberculosis. One is a type of injury: road deaths.
But if you consider a death to be the end of a human life, and if you consider an unborn human being to be a human life, then you may be interested in another article from the WHO: https://www.who.int/news-room/fact-sheets/detail/preventing-unsafe-abortion
Titled, "Preventing Unsafe Abortions", the article begins, "Between 2010-2014, on average, 56 million induced abortions occurred worldwide each year."
According to WHO's reckoning there are 56.9 million total deaths worldwide annually, but also according to WHO there are also 56 million abortions worldwide each year that are not counted as deaths because the WHO does not consider an abortion to be the ending of a human life.
I do. So I have corrected their "10 Leading Causes of Death" chart to reflect reality. Reality is NOT PRETTY! Nearly half of all deaths worldwide annually are human beings killed in the womb via abortion.
As I corrected the chart I had to consider what color bar to use. Abortion is not a communicable or a non-communicable disease. Abortion is a fatal injury to a human being.
