The deadly 2019-nCoV has been being in outbreak in Wuhan and around the China. Which has been spreading rapidly to at last 24 countries up to February 5,2020,[1]with Globally 24554 cases confirmed,outside of China 191 confirmed, 24 countries infected with 1 death.As of Fabary05, 24:00, 2020, a total of 28018 cases had been reported in China[2]. And the control of the outbreak has been in bad results up to now. The emergency treatment of 2019-nCoVpneumonia has been receiving little optimistic clinical recovery. Even China government and Chinese people have been managing to do the best to control this emerging infection outbreak.

In the wake of the 2003 severe acute respiratory syndrome (SARS) outbreak, and now, the 2019-nCoVoutbreak, in just 17 years the two outbreaks of the same family of the coronavirus have been developed deadly virus in the same country of China. Which seems that the mutations of the coronavirus were too rapidly.

AS we have known that the environment promotes and makes the biology gene mutation. And the mutation makes the virus and other microbiology as causative factors.So the deadly SARSvirus and 2019-nCoV have been mutated.

As the time goes on. The environment has been being polluted. And the deadly virus have been mutated. So theSARSvirus and 2019-nCoV mutated in China as deadly emerging infection outbreak can be said that the reason is environment pollution in China.

As the nature has been polluted with worse climate change and dry at present. Up to now, the polluted nature has not been prevented, to say nothing of cured. So the nature has been mutating the natural virus into deadly 2019-nCoV must not the last one in China, even in the world.

Therefore, as China has been being hit again by the deadly coronavirus. And which has been spreading around the world. The world and China have been being in emergency to control the outbreak and treat the deadly pneumonia. We must find the true reason how and why the deadly virus has been being produced. So that we can cure the etiology of the deadly coronavirus. And cure the deadly pneumonia as quickly and well as possible.

In this letter, in the time of emergency of the deadly outbreak of 2019-nCoVemerging infection in China and spreading around the world. The environment pollution is the reason of production of the deadly outbreak of 2019-nCoV and SARS coronavirus is put forward. Which may prevent the future another production of new deadly virus and other microbiology in China and other countries if my viewpoint was accepted and environment pollution was cured.
