In  The Green Lantern , a weekly environmental column, author Nina Shen Rastogi debated the impact of the carnivorous diets of pets on the environment.

She contended that the process of pets consuming offal that humans would not eat recycles animal parts while on the other hand, it takes resources like feed, land, fertilizer to produce such meat.

Her suggestions to pet owners on how to cut back their pets' carbon paw print were to reduce the pets' consumption of meat and/or feed pets with leftover human food, like meat and vegteables that would otherwise be thrown away.
