Global warming is threatening penguin populations by melting the ice they walk on and use as land. As ice melts, warming accelerates, leaving penguins without habitat. Polar bears are also suffering, some eating baby penguins out of desperation as their own habitat disappears. Individual actions like leaving lights on and TVs in standby mode contribute to pollution and global warming, indirectly killing penguins. Spreading awareness of these issues can help change behaviors and save penguins.
