Dog, the man’s best friend can also play a key role in environmental protection as per the study by the American researchers. The research says that most of the dogs have been slowly skipping eating meat and turning vegetarians. Mostly, the pet dogs have been preferring ‘meatless’ food of late.

According to the study, there are over 70 million dogs in the USA and most of these dogs consume meat and the pollution caused by meat is around 14.5% which might be low when compared to pollution caused by motor vehicles, and factories. But, the researchers claim the pollution caused by meat can’t be ignored.

On the other hand, most of the Americans have started turning vegetarians and forcing their pet dogs to get habituated to vegetarian food and playing their part in saving the environment.

With the ‘global warming’ going beyond the dangerous levels, the researchers in the USA started research on Animal Agriculture. In their research, they found that these animals are contributing 30% to the environmental effect. The researchers also revealed that it’s not possible to convert the Cats into vegetarians but it’s easy for the Dogs to convert as they are faithful.
