Hi, it's Pierce Brosnan here. I want to invite you to join Countdown. Now more than ever do we need to come out fighting. When you're backs up against the wall, you're come out slugging. So we have to go out there and we have to find and cultivate the finest minds in our

communities and globally and respectfully try and find a solution to this climate crisis.

Here's a talk from the Countdown Global Launch Event given by ecosystem ecology professor Thomas Crowther.

To hear more of these ideas and get involved,

The calm, tranquil feeling we all get is not a coincidence.

We all evolved in ecosystems like this,

where the sounds of birds and insects indicated the possibility of food, medicines, and all the

resources we need for survival. ecosystems and their biodiversity still hold the key to life

on this planet. I'm obsessed with this biodiversity,

the magic of the infinite network,

where every species depends on others to survive.

For most of my career,

I focused on just one of those fascinating connections

between insects and fungi in the soil.

I longed to understand the scale of these networks

and to understand how they might help us with one of the greatest challenges facing humanity, our rapidly warming planet.

The problem is clear. We know we need to reduce our emissions and draw the existing carbon out of the atmosphere.

Stop the damage and start the repair.

And this is where forests can help.

Like all plants, trees capture carbon from the atmosphere,

and they use it for growth.
