That is a sucker punch question.
Smithsonian museum sent a crew out toward the North Pole to film and make a story line of the wildlife and their environment for their "Earth" series. After 2 and half years they excitedly came back to the editing table to put it all together. But guess what, they were sent back because they had missed something. Something the editors wanted, just was not there. So, back they went for another 6 months. This background story is included in the "Extras" of the deluxe DVD set. They were to show the plight of Polar Bears because of "global warming", as it was called at the time. What they developed was a story of a PB so hungry, that poor judgment caused it to get gored by a Walrus. As it tries to snatch a pup it is caught by a Walrus and gets a wound that will fester and rot in its back leg. Nice thing about DVD is "quick back up" and pause. Eventually being interested in the fight action, one is slapped in the face with the wound being in the wrong place after the poor bear limps off with a bleeding spot. You can't believe your eyes, you back it up again. And say OK, but it's a good story, right. But later we get into those "Extras" and hear its own story of how the story came together. Business is business.
With this and so many other things, especially the selling of Carbon Credits, one realizes Smithsonian was paid to make a commercial plug. And that's OK, it's just a story. Later though our Canadian friends begin to complain that global warming is causing a Polar Bear population boom.
While it is easy enough to believe in global warming, it seems to be so shrouded in obvious propaganda. The entire cause loses all sincere credit and makes a concern that honest environmental causes are being wasted by a sweet con. Our atmosphere is being polluted. Vast areas of China have no birds or frogs. A continual 1,000 foot cloud of "Green" overshadows the island of Tobago any time the weather is calm. And we could go on. But the point is, Carbon emissions are the cleanest, softest and most eco-friendly emission there is. Come On!
