First, lets make it clear that I do not hate pets. I have owned a pet ever year of my life up until when I got married. I love dogs, I've had everything from 'Spaniels to Chow-Chows to a 100+ lb. Golden Retriever. Even now, I love visiting my mom and her new puppy.
But lets run some quick math:
Lets take a small city (not what we're building, but if we expect this to catch on lets really think about this)...
STATS FIRST:
Americans own more than 77.5 Million dogs and more than 93.6 million cats. Of a population of 300 Million Americans that means 1 in 4 houses owns a dog (on average) and 1 in 3 own a cat. The average cat weighs at least 8 lbs, and will eat 28 times their own weight / yr. That means 224 lbs of food per year, per cat. The most popular dog in America is the Labrador Retriever which has an average weight of 67.5 lbs. Information on exactly how much Labs eat is difficult to find but lets say its running lean, eating 20 lbs of food per month. That means, our dog is eating 240 lbs of food per years.
So lets say we have a city of 100,000 people... That means we could expect somewhere around 20-30,000 dogs, and 30-40,000 cats.
So 25,000 dogs X 240 lbs = 6,000,000 lbs / yr
And 35,000 cats X 224 = 7,840,000 lbs / yr
That means altogether we are providing 13,840,000 lbs / yr worth of food in a SMALL city of 100,000 people.
This does not take into consideration the special processing needs of the animals, for example, dogs require bone meal in their diet. Nor does this take into account well-care (what if the animal gets sick, the resources required to produce, maintain, and administer treatment) for the animals, nor does it take into account vaccinations, nor does it take into account their toys, what WE have to spend to keep our homes clean in their presence, or keeping US healthy in their presence.
In terms of pests, its well known that these animals can-and-do carry hard to exterminate pests like BED BUGS which have exploded in population in America.
So, 7.54 MILLION pounds of food for animals per 100,000 people. And thats not counting the above concerns. This isn't counting the pet gerbils, birds, lizards/reptiles. That is a SIGNIFICANT amount of resources.
Even to scale it down, lets say our city only has 5,000 people, we could be looking at 1.5 MILLION POUNDS of food for animals.
Here is the beauty of it. This isn't about me or you or even about right or wrong. Its above MONEY. I'm not saying we shouldn't have a food surplus, we should absolutely shoot for a food surplus every year, but that doesn't mean we'll actually reach it. Like I said, the REALITY of the situation is that there are lots of things that will surprise us along the way, stretching our precious-few assets thin to support some animals (as much as I love them) is not really an option.
Of course, it could be voted on, but I urge those who would cast a vote to consider whether they would sooner give food to an animal, or a hungry child.
