 Pets Play Major Role in Increasing Greenhouse Gas Emissions
In a new research, scientists have determined that pets can play a large part in increasing greenhouse gas emissions, with calculations indicating that a Land Cruiser's eco-footprint being about 0.41 hectares, which is less than half that of a medium-sized dog.


According to a report in New Scientist, the research was done by Robert and Brenda Vale, two architects who specialise in sustainable living at Victoria University of Wellington in New Zealand.

As well as guzzling resources, cats and dogs devastate wildlife populations, spread disease and add to pollution.

To measure the ecological paw, claw and fin-prints of the family pet, the Vales analysed the ingredients of common brands of pet food.

They calculated, for example, that a medium-sized dog would consume 90 grams of meat and 156 grams of cereals daily in its recommended 300-gram portion of dried dog food.

At its pre-dried weight, that equates to 450 grams of fresh meat and 260 grams of cereal.

That means that over the course of a year, Fido wolfs down about 164 kilograms of meat and 95 kilograms of cereals.

It takes 43.3 square metres of land to generate 1 kilogram of chicken per year - far more for beef and lamb - and 13.4 square metres to generate a kilogram of cereals. So that gives him a footprint of 0.84 hectares.

For a big dog such as a German shepherd, the figure is 1.1 hectares.
