Walruses have just recovered from an half century of being over hunted when a new even greater threat now threatens there existence. There is a decrease of coastal sea ice that walruses normally lay on so they are now migrating to 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. Because of the over crowded shores a large amount of walruses have been found dead do to being trampled and crushed.
I think that it is bad that because of humans causing global warming that we are effecting other animals and slowly killing them do to the raising temperatures. We need to try and reverse the effects of global warming so we can save the populations of animals that have been effected by global warming.
