UK blog discusses environmental impact of pets

A UK Guardian blog looks into whether or not pets are environmentally-friendly.
The blog says that views of whether or not a pet’s impact on the environment should be considered usually depend on if the person is a pet owner or not.
Each animal species has its own traits that affect the environment. The blog gives examples, such as cats hunt little animals, large dogs eat a lot of food and fish tanks require light switches to be left on constantly. Some measurements, like “carbon pawprints” may be useful to some looking to measure the impact of these animal attributes on the environment.
Readers are invited to share their opinion on the topic by making a post to the blog’s Web page.
