Psssss. Hey, smarty pants! Listen up and see if you can guess what I'm doing. Ready?

If you said that I'm walking my dog near the ocean, you're right. Yep, Luna and I love

walking on the beach. We love the ocean breeze, the sound of the waves, and the feeling of

the sand between our toes and paws. Ouch! I just stepped on something. What is this? A

plastic milk container? Where did this come from? I don't know any fish who drink milk?

Except maybe a catfish? No. No. Catfish do not drink milk. And random milk containers

do not belong on the beach. I'll just pick this up and throw it out in the trash can

there up ahead. Hey, smarty pants, what do you do when you see bottles or soda cans lying

on the ground where they shouldn't be? Do you pick them up? If you said yes, then believe

it or not, you're actually saving the environment from something called pollution. I'm sure you've

heard the word pollution before, but do you know exactly what it means? Pollution is something

that's added to the environment that is harmful or poisonous to living things. That's right,

pollution is bad for you too, Luna. Pollution could be trash, debris, or even poisonous

chemicals. But what exactly causes pollution? How does pollution affect the environment?

And what can you do to reduce pollution? Oh, good job, Luna. You found another milk

carton. It's time for another whiff of science, son. Who smarted? Who smarted? Who smart

is it you? Is it me? Is it science? Or history? Listen up. Everyone, we make smart

people. Let's run over and... Excuse me, you mind watching where you step in? Whoa, sorry,

didn't see you down there.

Whoa, is that a test tube you're holding? Well, it's not a small glass sandwich. Right,

don't you think? I'm an environmental scientist and I'm testing the beach sand for microplastics.

Smarty pants. Do you know what microplastics are? Did you just call me smarty pants? Oh,
