It's World Penguin Day, and there are reasons to mark it. It's not just that penguins are remarkable and funny and cute, as you can see here.
It's also that penguins are in trouble. Climate change is real, and it will affect animals and plants worldwide, including penguins. Many of the world's species of penguins (12 of 17, by one count) are experiencing population decline, due partially to habitat loss caused by climate change.
Want to help? Learn more about penguins and how climate change affects them. Support organizations like the World Wildlife Fund and Defenders of Wildlife that work to raise awareness, and work to protect penguin habitats. One group that I've mentioned earlier is Penguin Watch, where you can help researchers and look at cute penguin photos. Win-win!
