X'mas dishes boost global warming

The reserch team in Manchester university published one amazing reserch. It says that traditional X'mas dishes in Britain home emit much CO2 which is equivarent to driving around the earth 6,000 times! Because the ingredients of turkeies or roast vesitables, which Britains eat when X'mas are imposed from abroad, to impose them make much CO2. In addition, making ingredients and cooking also produce CO2 a lot. The reserch team says 8 portions emit 20 kg CO2. I think global warming is serious problem, however tradition is also important for people in that religion. We human shold cut CO2 in other activity such as translation and so on. I hope the time will come that everyone enjoy their tradition without any concern about emission of CO2. To realize this world, we should do hard for global warmming.
