Answer:
Many thousands of people die a day from different causes, such as drugs, poverty, murder, suicide, accidents, and cancer and other illnesses. This is much lower than the number of people born each day.

In 2011, the average deaths per day were 154,138 worldwide, compared to 363,554 births.
(To find other statistics, you can consult the related link below.)
About 250,000 - 300,000 people die per day.


Calculations:
7 billion people on earth.
Average life expectancy is about 66.12 years ~ 24150 days
7 billion people รท 24,150 days is just less than 300k
However, life expectancy is increasing, and population is increasing, so the actual number should be lower than 300k.
6647 persons dies every day.
