From Self Destructive Bastards Blog:
It has been calculated that the average dog has an ecological footprint about twice that of an average SUV. That is, twice the amount of land is needed to produce the resources required for the dog, as compared to the SUV. The average dog also produces about the same carbon emissions as a large car. There are over 70 million dogs in the US, and over 80 million cats. That's a massive environmental impact. The land use required to support our pets is contributing to deforestation and global warming.
I have cats and a truck or SUV as it may be called. I have to get the truck neutered so it doesn't reproduce.
So long truck nuts.
