Could Fungi Actually Be the Key to Humanity’s Survival?

90 percent of all land plants

need to have a plant-fungus-root association.

You can see the fungus, which exists in most of its life as thin filaments,

and the network of thin filaments, we call it mycelium.

And the mycelium of the fungus can tap into the root of plants

and make a symbiosis.

And thereby, they exchange nutrients that the other one isn't so good at making

or capturing.

But it doesn’t stop there,

because the fungi can tap into other plants at the same time,

So what you end up with is this massive underground network

mediated by fungi.

Now, it's not just nutrients that are flowing,

but also communication,

because plants can talk to each other through the fungal network

to create chemical signals to be able to warn of a pest attack, for example.
