If you haven't heard by now, CNN is debuting a special documentary called Planet in Peril next week. It's going to explore environmental concerns around the globe, and promises to be two great nights of television. 

We've been running video explainers about the topics covered in the doc on CNN Student News, and we asked for your thoughts about the program, and a number of you responded. A special thanks to the students from Bonney Lake, Washington!

And one teenager from Massachusetts, Casey Ehrlich, also sent us some pics of her great environmental outreach project: blankettheglobe.net. You can see more photos here.

A few more plugs for PIP: It has stunning HD photography, some cool music by R.E.M., and (guess what?) FREE curriculum perfect for your classroom, including pre-and post-viewing discussion questions.

Also, if you sign up for our free daily newsletter, you'll receive a Planet in Peril world map poster. (while supplies last)

This project is HUGE, and we're pretty proud to be a part of it. Be sure to check it out Oct. 23-24, 9 p.m. ET. And let us know what you think.
