Hello sir, if you see that tibetans are having only chinese food you should also see that tibetans are using mongolian dress, indian born religion (buddhism). Historically Tibetans were intelligent to adopt all good things from neighbours. Please be open minded. You are right in saying there is no vegetation in Tibet. But that is only a portion of Tibet. I suggest you first go there and then see which country has got more vegetation. There are abundant of pastures and forests which although had decreased substantially after Chinese occupation. Tibetans are not living in foreign nations by choice. They are forced to leave their home. Who in the world want to leave home voluntarily ? I am sure no one except insane. Only Tibetans know how it feels to be a refugee as a saying goes "only the wearer knows where the shoe pinches". You and me were born free so we can not feel the pinch. I think it is our moral duty to support them atleast emotionally. Otherwise the words humanitarian, justice et al will remain merely words without any real meaning. By Jaipur.
