Toyota Prius More Harmful than the Hummer?

So this is something i have been wanting to look up on google for a long time, due to people talking about it and Top gear the british car show. One one many articles -
"Building a Toyota Prius causes more environmental damage than a Hummer that is on the road for three times longer than a Prius. As already noted, the Prius is partly driven by a battery which contains nickel. The nickel is mined and smelted at a plant in Sudbury, Ontario. This plant has caused so much environmental damage to the surrounding environment that NASA has used the ‘dead zone’ around the plant to test moon rovers. The area around the plant is devoid of any life for miles.
The plant is the source of all the nickel found in a Prius’ battery and Toyota purchases 1,000 tons annually. Dubbed the Superstack, the plague-factory has spread sulfur dioxide across northern Ontario, becoming every environmentalist’s nightmare. “The acid rain around Sudbury was so bad it destroyed all the plants and the soil slid down off the hillside,” said Canadian Greenpeace energy-coordinator David Martin during an interview with Mail, a British-based newspaper." Also "The Prius costs an average of $3.25 per mile driven over a lifetime of 100,000 miles - the expected lifespan of the Hybrid.
The Hummer, on the other hand, costs a more fiscal $1.95 per mile to put on the road over an expected lifetime of 300,000 miles. That means the Hummer will last three times longer than a Prius and use less combined energy doing it."
This along with so many other articles was just shocking to me. In a nut shell to to the Prius "complex design and manufacturing process, more exotic materials, shorter lifespan, more expensive repair and disposal costs, and batteries, it actually costs more to drive than the Hummer". What shocked me the most is that it cost 50% more to drive than a hummer. Even more so is that the hummer while being a eye source is less harmful to everyone ells as a hole then the Prius. A Prius to me, up to now represented a "green" movement and i just think its a shame how far off from the truth we can actually be persuaded to think. I would really like to send some of the articles i have found to "environmentally friendly" celebs that drive them, an most likely yell at Schwarzenegger about his hummer every time they get the chance. Also don't you get a tax brake for driving a car that gets a certain mpg? Well i guess that just another thing thats not perfect about are government. Well befor this artical i wasent going to go sell my car and get a Prius and now im deffenetly not but i do feel better about driving my VW.
