So, I'd like to spend a few minutes with you folks today

法助動詞 B1

imagining what our planet might look like in a thousand years.

I need to talk to you about synthetic materials like plastics,

which require huge amounts of energy to create

I also want to tell you and share with you

have been using mushrooms over the last three years.

We're using mushrooms to create an entirely new class of materials,

which perform a lot like plastics during their use,

and are totally compostable at the end of their lives.

I need to talk to you about what I consider one of the most egregious offenders

This is a material you all know is Styrofoam,

but I like to think of it as toxic white stuff.

In a single cubic foot of this material --

about what would come around your computer or large television --

20 billion dollars of this material is produced every year,

and everything from building materials to surfboards

And that's not the only place it's found.

by volume, this material occupies 25 percent of our landfills.

- Even worse is when it finds its way into our natural environment --

on the side of the road or next to a river.

If it's not picked up by a human, like me and you,

it'll stay there for thousands and thousands of years.

is when it finds its way into our oceans, like in the great plastic gyre,

where these materials are being mechanically broken

Earth's respiratory and circulatory systems.

And because these materials are so prolific,

there's one other place you'll find this material, styrene,

which is made from benzene, a known carcinogen.

and there are three key principles we can use to guide these materials.

Today, we use a single feedstock, petroleum,

and make most of the materials you see around you.

and it's simply crazy to do this, to put a liter and a half of petrol in the trash

Second of all, we should really strive to use far less energy

I say far less, because 10 percent isn't going to cut it.

We should be talking about half, a quarter,

And lastly, and I think perhaps most importantly,

that fit into what I call nature's recycling system.

This recycling system has been in place for the last billion years.

and a hundred years tops, my body can return to the Earth with no preprocessing.

Yet that packaging I got in the mail yesterday

But nature provides us with a really good model here.

its solar collectors, these amazing molecular photon capturing devices --

it doesn't pack them up, take them to the leaf reprocessing center

and have them melted down to form new leaves.

It just drops them, the shortest distance possible,

where they're actually upcycled into next year's topsoil.

is, by using a part of the mushroom you've probably never seen --

analogous to its root structure; it's called mycelium --

with many of the same properties of conventional synthetics.

It actually takes things we would consider waste --

things like seed husks or woody biomass --

and can transform them into a chitinous polymer,

which you can form into almost any shape.
