This comic strip really brightened up my day! I love the subtlety of the message. Hopefully some people will remember this comic the next time they're at a beach. It's really speaking the truth!
Shells ARE the homes of all the mollusks. I think it's pretty obvious how their 'homes' are being compromised on land...(i.e. pollution, habitat destruction..the whole lot). But i don't think many people realise how the simple act of picking and removing shells from the beach affect these creatures. Well yes, the shells do keep growing as they grow, but other animals such as hermit crabs use abandoned shells as their homes. And anyway, by removing the shells, its taking away the natural calcium from the environment, meaning there's less calcium in the environment for other mollusks to build onto their shells.
And it doesn't only affect mollusks of course...i mean shells also contribute to the texture of beaches, of which turtles are dead sensitive to, and may cause them to abort laying their eggs. And it'll change the whole energy-type of the beach, which will change the shape and amount of sand, which has other consequences for many other things...you get the idea.
If you do the math again (i like math!), you'll realize there's a whole lotta things dying/changing out there just because of the lack of shells!
In any case, i heard from some of my sea buddies that there's an evil little mollusk called
Conus that's out to get anyone who tries to steal its beautiful cone shell by stinging them to death. So best be cautious and not pick any at all, lest they learn from him!
