Great ideas! I'm mentioning it in all my classes too, even if only 1 in every 50 students acts on it that is better than no positive action. Also seeing a lot of TV ads recently for environmental awareness...and a terrible K-pop song by some pretty boys called "save earth"...terrible song, good message. Lets ry and extend Earth Day to the M&G, by doing an emu parade at the finish of each day too (picking up whatever trash we see on the trails and at the crag).
