Environmentalism Response

This is in response to Dave's post about environmentalism acting as a threat or an opportunity:

Dave brought up a good point that social responsibility is important for companies because they would like to portray themselves as helping the community and reaching out to others, rather than just focusing on the bottom line. Dave brings up the point of the recent booming market for hybrid cars a couple of years ago, and how they are more fuel efficient, cut gas emissions, and are more eco-friendly, provides a positive view of these companies from the view point of the consumer, which is a good thing for the company. But, as Dave said, it also hurts the sales of the big gas guzzlers. I think that this cannibalism can have a negative impact on some companies. Their sales are being negatively affected by this surge in hybrid car sales, all as a result from trying to be more environmentally friendly. I believe that these car manufacturers have to be careful on how much they are going to market these cars, if it is going to cut into the sales of big gas guzzlers too much. Dave, do you agree that this marketing scheme of being "green" may eventually have a negative impact on some of these companies?
