It is shot very nicely, however I disagree with some of his key arguments. First, he says that the burning of waste wood increases CO2 in the Ozone. However, it would require the burning of fossil fuels to process that wood instead of burning it. Would he rather see these logging sites clearcut? Clearcuts are really ugly. The leftover debris protects the ground from erosion, as well as maintaining an ecosystem for small mammals and birds. There are larger problems with the practice of forestry, I don't think this is one of them. To make this relevant, you would need to interview foresters and ecologists, to give another perspective.

This is cool man. The effect is accomplished from when the lens zooms in more as the camera physically moves backwards and vice versa. What is taking place is the focal length of the lens is inscreasing. Larger focal lengths (IE telephoto lenses) tend to compress depth, whereas shorter focal lengths emphasize space. So as the camera zooms in the perceptual depth of the image is flattened. Another way to think about it is that the perspective is getting more acute. It looks like the background and the foreground are squeezing together. I think that the only way you could maintain a relatively unchanged background is if it was very close to the subject, otherwise it will be very noticeable. However, that is the point of the effect in the first place.
idmiller: yes, this effect was first seen in Alfred Hitchcock's Vertigo, AKA. the vertigo effect. -
