From humpback whales to monarch butterflies, through eels, sharks and fruit bats: they are all migratory animals and are increasingly at risk of extinction, everywhere in the world.
This is indicated by the first UN report called 'State of the World's MigratorySpecies' which shows that 1 in 5 migratory species is at risk of extinction, a particularly dramatic situation is for migratory fish, 97% of which are at risk of disappearing.
The cause is in particular the reduction of habitats due to human exploitation and climate change as well as indiscriminate trapping.
Performing migrations is a strategy adopted by many animal species that allows them to follow the best environmental conditions and have food available more easily.
These are often animals that have a fundamental role in regulating the balance of the ecosystems into which they periodically move and in many cases they are the protagonists of incredible journeys - such as that of the Black Godwit, a bird that is able to fly without stopping for 13 thousand kilometres, moving from Alaska to Tasmania, or eels that are all born in the Sargasso Sea and then spend their lives in rivers around the world and finally return to lay their eggs in their place of origin.
