You thought that the threat of chocolate and coffee shortage was bad! It turns out that climate change is also causing animals, including sheep, deer, birds and reptiles to shrink.

Researchers warn that warmer temperatures over the past few years have made some animals adapt to need less body fat to survive, while others are struggling for food. They expect that evolution will probably favor small animals who are better able to keep up with the energy demands, as resources fluctuate on a warmer planet.

The study, published in the journal Nature Climate Change also warned that shrinking crustaceans and fish could also adversely affect people who eat them.
