The peace and quiet of the forest. Huh, what a perfect place to relax.

Except not all of these trees are safe for humans to touch.

Believe it or not, some trees are so hazardous that, even standing too close, can be a death sentence.

There are trees that produce deadly poisons, trees with trunks lined with thorns, and trees whose

seeds explode with the force of a hand grenade.

Suddenly the forest doesn't seem so relaxing.

So let me be your guide, as we explore some of the world's most dangerous trees and

plants that you should never, ever touch. You're listening.

You're listening.

You're listening.

You're listening.

I'd be amazed.

If you're ever lucky enough to find yourself relaxing on the beaches of the Caribbean,

you might think the trees lining the coast could provide some well-earned shade.

But if you notice that the trees are marked with a series of red bands, you need to pick

up your towel and your water wings and run away from there as fast as you can.

That's because this is the Montchonil tree, one of the most toxic trees in the

entire world. The milky white sap the tree excretes is packed full of skin irritants,

which are strong enough to cause blisters on contact, and even second-degree burns.

The irritants in this sap are so dangerous that if even a drop were to land in your eye,

it could cause blindness, and that's just the beginning.

The sap can dilute into rainwater, making it dangerous to even stand underneath as the solution drips off wet leaves.
