Alas, there is the anti-natalist side to the satire:
OK, it’s true. We could have done better. By not having three kids we could have saved the atmosphere from an extra 28,223 metric tons of C02 each year — or 58 times the amount that we have saved by switching to a fuel efficient car, driving less, recycling, installing CFLs, replacing our inefficient refrigerator and old windows. And by adopting rather than conceiving, we would not have added to the 350,000 children who are born every day to a planet now burdened with 7 billion humans, and braced for more.
