The message that all the learned people who have appeared on this live broadcast have passed on to the viewers has been the urgent need to address the problem of global warming before Polar Bears and the habitat in which they live are lost forever. Reducing the "carbon footprint" is fast becoming the mantra of the conservation organization that brings the experts together to answer questions live on camera from the frozen tundra. This is the same organization who has declared 2008 the year of the Polar Bear and is organizing a series of tours to Churchill to view the bears and commemorate this occasion. No doubt these people are coming from around the world. The question I have is an obvious one, how does hundreds of people flying from around the world to Churchill then get on a tundra bus to travel across the tundra to an outcamp do anything at all to reduce the carbon footprint. Is the cost to the environment justified, does the conservation organization hosting these events believe the "awareness to the plight of the polar bear" these events generate cancel out any or all damaging carbon emissions produced to get these people out onto the fragile environment not forgetting the refuse and waste that has to be delt with which in an subarctic environment is a huge problem.
Looking foreword to your answer.
