[FOREST SOUNDS]
Welcome to the mountains of central Mexico.
This is the site of one of the greatest events in all of nature.
The annual monarch butterfly migration.
Every year, tens of millions of monarch butterflies fly to these mountains from all over the eastern
United States, as far away as Canada.
They come here to beat out the cold back home, to basically chill, and while they're here
they're basically hibernating, living off stored fat until the temperatures get a little
warmer, the days get a little longer, and a signal inside their bodies tells them it's
time to return home, to start the next generation who will continue this tradition.
Next year, and hopefully every year after.
It is one of the most amazing things I've ever seen and you have got to check it out.
It's just down this path.
Let's go.

That was pretty awesome, wasn't it?
This amazing event, well, it's under threat.
It's under threat because of threats to this place we are now, but also to the entire migration
path that takes these butterflies north and south every year.
We all have to do our part to make sure they have enough to eat, places to lay their eggs,
and a place to come back to.

migration, and maybe even what you can do to keep it going.
