The You-tube video of the Harvard professor is not the same one. This one is a Doctor and he is very concerned. All trade and travel to and from China should be banned. Maybe some American companies will wake up and bring their factories back home. At least to smaller countries.

One of the reason almost all flu viruses originate in China is because they grow chickens and hogs together. Throw some bat droppings in their feed troughs and you get bird flu going to the hogs then to humans and back and fort the virus mutates so a new virus emerges every year. Chicken dropping are half undigested food and the hogs will eat it mixed in with the hog food. Auburn university has experimented with drying the chicken droppings and pouring molasses over it and feeding it to cattle. At least we dehydrate it and between the dehydration and sugar in molasses it kills germs and viruses. China could care less as they have 1.4 billion people to feed. A few thousand people who die a year doesn't concern the Chinese communist government. Even the UN has asked China to try to change their agricultural practices to cut down on the flu.
