The Numbers
The Prius' battery contains nickel, which is mined in Ontario Canada. The plant that smelts this nickel is apparently nicknamed "the Superstack" because of the amount of pollution it puts out; the area for miles around it is a wasteland because of acid rain and air pollution.
Here we go again. This is typical. If you don't like something, scream loud and long -- in a shock and awe campaign -- until your opponents cover their ears and go home; they will not even yell "Enough!" before fleeing because it cannot be heard over the din of the screaming. It does not even matter what is screamed; it is usually gibberish. If you are going to criticize, please use current sources or at least use verified-as-correct sources. This story is ancient, and it is incorrect.
Yes, the Prius' battery does contain nickel but that is NOT the first time it has been used in cars and trucks. Nickel is used in chrome plating. It is also used in stainless steel, which has prevented your exhaust system from rusting out every 3 years or so and falling on, and polluting, our roads.
Yes, nickel is mined in Sudbury, Ontario, Canada, which, in the early 1970s, was a true, barren waste-ground. It was so bad that urban myths arose that NASA did not land on the moon, but shot the whole thing for primetime TV in Sudbury. The city and its surrounding areas has, however, been really cleaned up in the past 30 years. It is now quite a green city and has earned awards for its regreening program.
Yes, it was the building of the Superstack, the skyscraping chimney that spread the sulfur gas emissions much further away (and spreading acid rain much further away), that allowed Sudbury to clean up its immediate environment, but the emissions now, in the current day, have been scrubbed clean, leaving largely carbon dioxide and water vapour (steam) as the largest components. Exhaust as steam is visible as white smoke, which makes the problem seem much worse than it is, but it is merely water.
