Over the weekend, I got into a discussion with a good friend of mine about climate change. What began as a friendly, casual interchange soon developed into one of those exaggerated conversations. You know the kind: where each person temporarily adopts extreme and opposing views, simply the hopes of spicing up an otherwise tepid chat. (Editor’s note: no punches were thrown, but tears were definitely shed.)

Anyway, here’s the gist of our discussion: The 1990s (as I remember it) was a time when individuals were encouraged to become more aware of their consumption habits. Remember the three “Rs”: Reduce, Reuse, Recycle? Remember the UN Earth Summit of 1992, and the resulting Rio Declaration? Remember Jessie Spano launching her “No Oil at Bayside” campaign? (Please excuse the “Saved by the Bell” reference – it is the work of the author and may not represent the views and opinions of GetSolar.) The point is that, back then, we were encouraged to make small personal sacrifices in the name of the environment, often by agreeing to consume less “stuff.”

Fast forward a dozen years and the opposite seems to be true: we’re not called on to consume less, we’re just encouraged to consume differently. From the “Red Campaign” and carbon offsets to organic food and the Prius, there are an increasing number of ways to “vote with your dollars.” People aren’t consuming any less, which makes this approach economically viable. And, since a cup of organic coffee is still a cup of coffee, individuals don’t have to make any major lifestyle adjustments in order to lead a “greener” existence.

Ultimately, my friend and I disagreed (or at least pretended to disagree) on whether this new paradigm – which requires no personal sacrifice and does little to reduce consumption – was a “good” thing or “bad” thing. This is, admittedly, the debate that lies at the core of sustainable development. And while I’d love to continue on this topic for several more paragraphs, the responsible blogger in me thinks it’s better to stop here and invite others to add to the discussion.
