80% of the diseases are related to drinking water pollution. Do you drink enough water?

June 5th each year is World Environment Day (World Environment Day).
Perhaps one day we will find out how powerful the human environment is, and how fragile the environment for which the human race depends!
According to 2016 March issued by the WHO, "disease prevention through environmental health: environmental burden of disease global assessment report (Second Edition)" we can know: air, water and soil pollution, chemical hazards, climate change, ultraviolet radiation and other environmental risk factors can cause 100 kinds of diseases and injuries.
1. in 2012 alone, a total of 12 million 600 thousand people worldwide were estimated to have died from living or working in an unhealthy environment, close to the global death toll of 1/4; Of the 21 thousand and 260 deaths, about 820 died of stroke, heart disease, accident, cancer, chronic respiratory tract infection, non infectious diseases, accounting for about 65%; 3. because of the improvement of environmental sanitation and medical services, the number of infectious diseases such as diarrhea and malaria related to the decline of bad water supply, environmental sanitation, waste management and garbage management has declined globally during the period of 2002~2012 ten.
The world’s largest single environmental health risk: air pollution According to the statistics of the World Health Organization, in 2014 92% of the global population living environment air quality failed to meet the WHO air quality guidelines about air pollution level; in 2012, killing 7 million people, air pollution has become the world’s largest single environmental health risk.
Based on the 2012 death data and evidence about the health risks associated with air pollution, the WHO analyzed the following set of data for diseases and deaths caused by air pollution: Among the deaths from outdoor air pollution – 40%, ischemic heart disease; 40% stroke; 11%, chronic obstructive pulmonary disease; 6%, lung cancer; 3%, children with acute lower respiratory tract infection; Among the deaths caused by indoor air pollution – 34% stroke; 26%, ischemic heart disease; 22%, chronic obstructive pulmonary disease; 12%, children with acute lower respiratory tract infection; 6%, lung cancer.
Polluted water sources can not only be used, but also spread all kinds of infectious diseases such as diarrhea, cholera, dysentery, typhoid fever, poliomyelitis, etc.. Water health and safety are guaranteed, and at least the following diseases and hazards are avoided: (water pollution hazard).
Each year more than 500 thousand diarrhea deaths result from drinking water pollution; 2. diseases such as malaria, dengue fever and other pathogens are water carriers; 3. diseases of the life cycle of Schistosoma mansoni and other pathogens in water; 4. arsenic poisoning and fluorosis caused by chemical pollution water sources; Status of water pollution in china.
After industrialization and city hurricane style development, in China there are about 2/3 of the land subject to different degrees of pollution, especially the problem of heavy metal pollution in soil increased significantly expand the risk factors causing soil heavy pollution and high risk.
