Your Pet Is a Global Warming Machine
Though some environmentalists love their dogs more than they love their Sierra Club reusable water bottles, a single dog can have a bigger ecological footprint than an SUV. And cats aren’t much better. According to research highlighted by the New Scientist, it takes an estimated 1.1 hectares of land per year to create the chicken and grain that a large dog eats for its food. A Toyota Land Cruiser SUV, driven 10,000 kilometres a year, would use .41 hectares of land, less than half that of the dog.
“Owning a dog really is quite an extravagance,” Dr. John Barrett of the Stockholm Environment Institute in York, UK told the New Scientist, “mainly because of the carbon footprint of meat.”
Cats and dogs also wreak havoc on the local wildlife. The estimated 7.7 million cats in the United Kingdom kill more than 188 million wild animals every year. And cat excrement, which can contain the disease Toxoplasma gondii,has been blamed for killing sea otters (and may have a hand in causing schizophrenia in humans, according to RadioLab).*
The New Scientist has some suggestions of how to lessen Fido’s ecological “pawprint,” including feeding him more environmentally friendly foods. Perhaps forcing people to consider the impact of their pets may keep the carbon footprint on a leash.
*Correction: The word “can” has been added to this sentence. Millions of people are infected with Toxoplasma gondii, according to WebMD, and cats are one of the most common ways that people can get it. Though not all cat cxcrement contains the disease.
