Tattoos: Are they good for the environment?
...
Planet Green recently looked into the topic and found that the Food and Drug Administration (FDA) does not regulate "any tattoo inks for injection into the skin, and many ink pigments used are industrial strength colors suitable for printers' ink or automobile paint.” The American Academy of Dermatology further details traditional tattoo ink’s not-so-green ingredient list: “Tattoo pigments may contain industrial organic pigments, including azo and polycyclic compounds, sandalwood and brazilwood, as well as aluminum, cadmium, calcium, copper, iron, phosphorus, silica, sulphur, titanium dioxide and barium sulphate, each of which may be the cause of a skin reaction like a rash or be toxic.”
Additionally, some black ink used in tattooing is animal bone burned down to charcoal while the “carrier” solution in the ink may contain glycerin derived from animal fat. So while Gary may not eat any animal products, he’s certainly found a unique way to wear them.

That said, it could be the case that Gary has his “work” done at a vegan-friendly tattoo parlor where no animal-based inks are used. There are several out there including Scapegoat Tattoo in Portland, Ore., Daredevil and FunCity Tattoos, both in New York, and Only You Tattoo in Atlanta. There’s a full list of such business over at Vegantattoos.com. Apparently, veganism and tattooing often go hand in hand, with many tattoo artists themselves abiding by strict vegan lifestyles.
