Yes, Earth Day is almost here. It falls on a Tuesday this year, so many folks are observing and acting on it this coming weekend.
One easy thing you can do is read the comics. Jim Toomey, who pens Sherman's Lagoon, is dedicating the current week to shark issues, and this Sunday's strip will be an opportunity for you and yours to get involved. You can see the details here, among other places.
Get the word out. Contact the National Marine Fisheries Service to encourage them to protect sharks. Contact your representatives in Congress to support the Shark Conservation Act of 2008.
