Human activities are destroying the natural world, leading to the extinction of animal and plant species at a terrifying rate.

Our actions threaten over one million species. And in New Zealand we have the highest proportion of threatened native species in the world, with more than 4000 at risk.

Some experts believe we are in the throes of the sixth mass extinction. In This Is How It Ends, a seven-part Stuff documentary series, Andrea Vance and Iain McGregor investigate the biodiversity crisis.

They are our lungs but New Zealand’s treasured native forests are dying.
