Many different species of animals, like salmon, frogs, robins, squirrels and polar bears, are shirking in size according to a new study.
The authors of the study say that the shrinking is due to global warming but other experts say that they might be taking it too far and that it may just be natural changes.
Some plants have also been shrinking, such as corn, cotton and strawberries.
"There is a trend in a number of organisms across the board from plants to big vertebrates getting smaller. The theory is as things get warmer they don't need to grow as large."
A different researcher said that you can't blame global warming exclusively:
"Changes in body size are a normal phenomenon. When conditions are favorable, they increase in size or reproduce at higher rates, and when conditions are deteriorating, they do the opposite. I think that most species will adapt to climate change and survive. No need for alarm."
Seems like the authors of the study might be the only ones truly blaming global warming. A Stanford biologist, who is an expert in climate change, said the study's conclusions:
"[…] seem kind of far-fetched."
All we know is, pocket-sized polar bears sound pretty awesome to us.
