Walruses Suffer Substantial Losses as Sea Ice Erodes

Recently, the walrus population has just recovered from over 50 years of being over hunted when a new, and greater threat now threatens their existence. There is a large decrease of the ice surrounding the coastal sea. This is where walruses spend most of their time. Because of this they are now migrating towards the rocky shores of the United States and Russia. With the sea ice melting the walruses have become very cramped on the shores where they are now going to. Their over crowded shores are a large amount of walruses have been found dead do to being trampled and crushed.
I think that it is bad, this is because the humans is one of the biggest cause for global warming. It effects all other animals and slowly kills them.eed to try and reverse the effects of global warming so we can save the populations of animals that have been effected by global warming.
