It’s hypocrisy to want to “keep the character of the neighborhood” and have more than the bare replacement number of children, since you’re creating a change in the demands on the neighborhood.
Most writeups of population growth rates and the economy focus on the economic benefits of more children, not the quality of life for the future generations. Future generations will not miss a Monarch butterfly or any species of tortoise or rhino just like we don’t miss the passenger pigeon or herds of a million bison, or being able to see a Milky Way we’ve only heard about. They might, however, be a bit put off by the water quality we’ve left behind, and let’s face it, we’re not all going to see an unspoiled wilderness because there’s relatively little left. Night sky is already abuzz with satellites.
