GLOBAL WARMING--- IMPACT OF VANISHING SEA LIONS |
| Sea Lions are kind of like a barometer for the environment. They have been dying in large numbers off the western coast of the United States. An example of the interconnectedness of the world, because of the sea lions dying, killer whales no longer have a large supply of food so they have been killing more sea otters, sea otters keep the sea urchin population in check so with fewer sea otters there are more sea urchins, sea urchins eat kelp so without sea otters to eat them, they have been consuming swaths of kelp gardens and threatening fish nurseries. color-reduction woodcut image size 19” x 23.75” price $700 |
