Every April 22 we celebrate Earth Day, and remember why it's important to take care of our home.
Organized by the Earth Day Network, the annual holiday celebrates protection of the planet and urges many to ramp up their efforts to ensure a sustainable future.
So, in honor of Earth Day, here are 12 reasons why we need to protect the Earth:
These polar bears
These happy dolphins
This baby orangutan who feels most comfortable hanging onto mom
These too-fuzzy-to-handle lion cubs
This penguin who has to be within a wing's length of her zookeeper
