1) I'm of the opinion that when it comes to the environment the key is not what you drive (hybrid vs. conventional) but how much you drive. Tree huggers don't seem to understand this.
2) I'm of the opinion that hybrids can do as much - if not more harm to the environment than non-hybrids (of comparable size catagory, not talking about a Prius vs. Hummer).
3) Also as long as I'm living in USA (or North America - for auto purposes I'm clumping Canada and USA together) I will chose to buy cars from USA-based manufactures assembled / made in North America. I've done it thus far and I don't have any problems with my vehicle (Ford). Like I said - it is my choice and will continue to be that way until the imports make something that is far more superior or my vehicle turns out to be a lemon.
4) I have a feeling you will next ask me whether I chose to buy clothing, electronics, etc. from USA-based companies or whether I shop at Wal Mart, etc. etc. etc. I don't want to discuss that right now - mainly because clothing, furniture, electronics, etc. the situation is more complicated (USA based companies having their goods made by China, etc.).
