Wednesday, April 22 is Earth Day, and a special edition of CNN Student News brings you a world of resources (get it?) to mark the occasion.  From the struggles of crab fishermen in Chesapeake Bay to the efforts of engineers to turn buildings green, we discuss an array of environmental subjects and show ways in which YOU can help keep the world cleaner.

Now the question is, are you currently doing anything to help the planet?  Do you recycle or try to cut down on trash, or are you doing anything special to celebrate Earth Day?  Give us a sense of what it means to you by responding right here!
