Just because something isn't "environmentally important" (whatever that means) doesn't mean you can't optimize it. We need to shift into the mentality of thinking about the environment. Don't slap the hand that's interested in making a difference.

You can optimize small things, but it will only have a small effect.

Better than nothing, sure, but the danger is that you only deal with the small things because you're not even aware of the big ones.
