(No, I'm not being serious. The topic just reminded me of when I once jokingly justified a poorly estimated ETA on a "simple" development project by referencing the above paper.)

Forcing breeders out of the city and making it inconvenient to buy pets locally will also encourage people to consider the reasons that is being done. I am not familiar with any other significantly effective way at educating the masses about the pros and cons of shelters vs. breeders. It's not a black and white issue. Many shelter animals are not problem-free, and many pet owners and breeders are responsible pet caregivers. Without actually working in an animal shelter and personally euthanizing scores of otherwise-adoptable animals, I don't know how the "average" person could be convinced that shelter animals are often just as loving and healthy (if not healthier) than animals bred for purchase.

How is this news, I thought that was the whole point of g-strings.
