Sara Moreno, Tatiana Pina and Martí Domínguez, researchers at the University of Valencia, have shown the over-representation of iconic animals of climate change, such as polar bears and penguins, in cartoons that address the climate emergency. In a scientific article, for which they have reviewed 1,022 of these illustrations, they conclude that, regardless of their geographical origin, cartoonists tend to avoid the use of native animals and show very little biodiversity in their drawings, especially in terms of insects and other invertebrates.
