Climate change not only affects humans, it is also having a significant impact on animals around the world. Experts believe that the Arctic sea ice is melting at a rate of 9% per decade due to global warming. As a consequence, many polar animals are at risk. For example, polar bears hunt, rest and raise their young on sea ice. Their main food source is seals, which they can only hunt on the ice. As the ice melts, it is harder for polar bears to survive and consequently many polar bears are dying. Sea turtles leave the ocean to lay their eggs on nesting beaches. However, because sea levels are rising, nesting beaches might disappear. Therefore, turtles will not have a place to lay their eggs in the future. Furthermore, the temperature of a turtle's nest determines whether eggs are male or female. Warmer temperatures result in female eggs. In the future, there might be more female than male turtles so turtle populations will be under threat.
