Hardly. I'm saying we need to do a million times as much.
Imagine pushing a boulder down a hill. Buying more efficient light bulbs is akin to pushing the boulder less. Or imagine charging money to your child's credit card and amassing a large debt. Buying more efficient light bulbs would be aking to spending less on the card, but still spending. We need to stop pushing altogether, get out in front, slow it down, stop it, then push it back up the hill. We need to stop charging money to our children's credit cards, start sending money to it, pay it off completely, and start putting money in savings.
Buying more efficient light bulbs isn't even in the same ball park with what we have to do save the planet. I'm not advocating giving up, I'm advocating changing the focus and doing a million times more to save ourselves.
