Salut! J'aimerais avoir une correction de ce commentaire.Pourriez-vous m'aider svp? 
To present this document, we could say that it consists of a video. It deals with a documentary on polar bears which live on the Hudson Bay, in the northeastern part of Canada. From the doctors and the scientists, we can deduce that this video is an advert that denounces that the eco system is in danger.
To sum up the video, we could say that it is about an animal documentary on the life of polar bears. We find several interviews on persons there studying this animal, as doctor Lunn there. According to him, polar bears are sending a warning signal because the eco system is in danger.
I am now going to comment on the journalist's views which are presented in the video. As I pointed out earlier, this video talks about the polar bears living in Wapusk National Park, which is situated in Hudson Bay. The doctor Lunn has spent twenty years studying polar bears. He thinks that they are sending a warning signal because they are in danger. Indeed, they are forced ashore earlier because the ice melts sooner. So they are coming ashore lighter and lighter. However, thanks to the tests made on polar bears, scientists have been building a huge database on polar bears.
I really appreciated the video because the polar bear is one of my favourite animals. I gave me the desire to know it more on this animal.
Merci d'avance pour vos réponses!
