And don't use lawn chemicals.

I just don't use toxic lawn chemicals at home.

You just don't need to expose yourself to that.

The next big category, and one, unfortunately, I'm an expert in, is heavy metals.

Mercury, lead, cadmium, arsenic.

These are a big one.

And often, this is not well understood.

Heavy metals like mercury lead, cadmium, arsenic, these are all naturally occurring in the environment, but they're usually buried.

Like coal has a lot, but that's buried under the ground, right?

Modern exposure levels can be harmful because we basically dug up all this coal.

We've burned it in cement plants, in energy coal burning plants, and...

it's created huge amounts of pollution.

In fact, Seattle has really high mercury in its environment.

Why?

Because of China.

Because China uses so much coal burning, it goes up in the atmosphere, it comes over, it's not acid rain, it's heavy metal rain, literally.

A lot of people are exposed.

So if you eat fish,

like tuna or swordfish or almost any fish, unless really little fish or certain regionally farmed fish.

And I like cetopia.fish.
