     World No Tobacco Day is observed around the world every year on May 31. It is meant to
encourage a 24-hour period free from all forms of tobacco consumption (消费) across the globe.
The day is further intended to draw global attention to the widespread prevalence of tobacco use
and to negative health effects, which currently lead to 5.4 million deaths worldwide annually (每年).
     The member states of the World Health Organization (WHO) created World No Tobacco Day
(WNTD) in 1987. In the past twenty years, the day has been met with both enthusiasm and resistance
across the globe from governments, public health organizations, smokers, growers, and the tobacco
industry.
     The WHO cites (提到)tobacco use as "one of the biggest public health threats the world has ever
faced." Tobacco is the number one preventable cause of disability and death. Tobacco can have many
negative health effects; it is a risk factor for six out of eight of the leading causes of death in the world,
Such as cardiovascular (心血管的) disease, lung diseases, and various cancers. The WHO blames 1
in 10 deaths worldwide on tobacco use, which equates to 5.4 million today. By 2030, they estimate
that the number of tobacco-related deaths will have risen to 8 million. Because of these issues, tobacco
consumption is seen by the  WHO as a key public health issue.
     WNTD is a part of the WHO's larger strategy to change tobacco-related thinking and behaviors
around the world with the aim of making the world healthier. According to the WHO, the point of
World No Tobacco Day is to ask people to give up using all tobacco products for 24 hours in order to
begin breaking their addiction to the "harmful and wasteful habit." The day is meant to raise awareness
about the health risks associated with tobacco and advocate far better polices to reduce consumption
worldwide.
