Marine litter effects on land

As usual human cause water pollution by dumping rubbish,litter in oceans. This litter causes death in some organisms since for example peguins in the Arctic can get pieces of plastic stuck around their necks or some fishes eating pieces of plastic as they mistake it for food cause population destruction for some species. Land organisms for instance bears and red coastal wolves depend on salmon fish during spring time when they come out of hibernation. Salmon fish thrive best in deep sea cold water's, and if litter thrown into ocean affect organisms, can thus affect food webs. Therefore if the salmon population is affected, this can therefore affect the land creatures who depend on the salmon fishes as a main source of food. Meaning that if the salmon become contaminated from the litter, the land animals can also be contaminated. This is termed biomagnification, the transfer of contaminants through a food chain.
