Answer:
Short answer is yes, the Prius is more bad than good for the environment. People can speculate about the future improvements, or how it gets good gas mileage, but keeping all of these factors in mind, from manufacturing, from the life cycle use of the product, and then how the product can be disposed or recycled, the Prius is actually very bad for the planet. So from the first model to todays current model, they produce toxic gases. A Partial Zereo Emission Vehicle or PZEV is cheaper, runs clean, and the manufacturing is not as bad as the Prius.
Do not take my word on it, Toyota themselves has made this announcement:

Ok, first of all Toyota does not simply throw out their batteries. Second of all none in the USA Market have simply worn out and been disposed of. It is not 1 big battery, it is 12 small batteries. These batteries can be fully recycled. How about you actually post something based on facts. Ive seen the recycle process for salvaged batteries in salvaged cars.

You should take your own advice. No one mentioned that the batteries CANNOT be recycled. READ the link Iposted that directly quotes toyota. They state....toyota that is, the people that make and design the prius by the way, they state that it takes more energy to produce and recycle the battery than it saves, also it puts out more pollution from the battery to the electronics onboard such as the electric motor, than a PZEV would. Because of what the battery's present to the environment, chemical and corrosive wise, the way they are handled and the extra energy to just transport, store, handle, and recycle the hazardous material far out weighs the product's (the battery's) total life cycle. More energy is used than saved from first making it to finally recycling it. I cannot say this any more simpler.
