But what happens to these large cetaceans and how to explain the multiplication of these events? Lamya Essemlala, the founder and president of the NGO Sea Shepherd France, has her idea. She points to noise pollution from ships. “The common point of all these animals is that they are cetaceans and, therefore, they orient themselves with their sonar. There is the question of noise pollution, in particular because there is maritime traffic which intensifies. But the sonar allows them to orient themselves, to feed themselves, to communicate… It is vital, for them”reminds TF1 of the president of the NGO.
In addition to noise pollution, there is also plastic pollution, which is omnipresent in the oceans, and the consequences of global warming, which disrupts their diet. “The melting ice can mislead animals, they think they are in the Atlantic when they think they are still in the Pacific”explains Denis Ody, head of the “Cetacean” program within the WWF association. “If the water warms up, the resource disappears and the whales could also be forced to change the way they feed, or even leave the Mediterranean”worries this doctor in oceanology.
