The polar bear, is affected both by the reduction in sea ice and by reduced stocks of its primary food, the ringed seal. Sea ice is decreasing throughout their Arctic range due to climate change. Ice reduction decrease the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction. Rising temperatures means that large areas of the ocean that were once frozen throughout the year now become open water.
Climate change directly affects the reproduction of sea turtles in three ways. First, sea level rise will affect significant nesting beach areas on low-level sand beaches such as Bonaire, the Maldives and the Great Barrier Reef. Second, rising temperatures increase the chance that sand temperature will exceed the upper limit for egg incubation, which is 34 degrees C. Third, rising temperatures bias the sex ratio toward females because temperature during incubation determines the sex of the egg. Loggerhead turtle nests in Florida are already producing 90 percent females owing to high temperatures, and if warming raises temperatures by an additional 1 degree C or more, no males will be produced there.
North Atlantic right whales, which can grow to more than 55 feet long and weigh 70 tons, range from Nova Scotia to the southeastern United States and migrate the length of the East Coast. Today there are fewer than 500 right whales left in the world. These animals have been protected since 1935 and listed as endangered since the early 1970s.
THERE ARE SO MANY OTHER KINDS OF OCEAN ANIMALS ARE AFFECTED BY CLIMATE CHANGE. THE PLANET ONT ONLY BELONGS TO YOU ALSO BELONGS TO THESE LIVES. PLEASE GIVE THESE LIVES A CHANCE TO LIVE OTHERWISE YOU WILL BE LONELY IN THIS WORLD OR YOU WILL BE NEXT TO DISAPPEAR FROM THIS WORLD.
