Sounds from around this beautiful planet will be updated here weekly

The world is literally getting quieter - and not in a good way. Since 1970, we've lost nearly 70% of Earth's wildlife populations, and with them, the natural symphony that once filled our planet.

That's such a striking way to think about extinction - not just in terms of numbers, but in terms of silence. And this story about sound recordist Martyn Stewart really brings that home.

You know what fascinates me? He started recording nature's sounds when he was just 11 years old, back when the world had only 3.5 billion people. The recordings from those early days capture something we can barely imagine now - nightingales filling English evenings, wolves howling under Alaskan moons.

And now when he returns to those same locations, what used to take minutes to record can take days. It's like nature's orchestra is missing most of its musicians.

The statistics are pretty devastating. Beyond that 69% decline in wildlife, we've lost up to 75% of insects in some areas. Most people don't think about insects, but they're literally the baseline rhythm section of nature's symphony.

That makes me wonder - what exactly replaced all those natural sounds?

Well, Stewart describes it perfectly - the constant drone of traffic, the whine of development, aircraft noise slicing through skies that used to carry nothing but bird calls. We're basically drowning out nature's voice with our own noise.

The part about recording the last Kauai oo bird is heartbreaking. Imagine being there, knowing you're documenting the final notes of a species that will never sing again.

And here's what's crucial to understand - these aren't just beautiful sounds we're losing. They're vital communication networks. Birds warning about predators, frogs indicating clean water, forests sharing information about danger through sound. When we lose these voices, we're breaking down entire ecological communication systems.

That reminds me of research showing how noise pollution affects everything from bird breeding patterns to plant pollination. It's all connected.

Exactly! And Stewart makes this brilliant point about how silence in nature isn't peaceful - it's actually a warning sign. It's like walking into a usually bustling city and finding it completely empty. Something's very wrong.

The way he describes wetlands really struck me - they've been halved globally. That's not just habitat loss, it's the disappearance of entire acoustic environments.

You know what's fascinating about wetlands? They have unique acoustic properties that help animals communicate more effectively. When we drain them, we're not just destroying habitat - we're literally changing how sound travels through the landscape.

That's such an interesting perspective - thinking about ecosystems in terms of their acoustic space.

And in healthy ecosystems, different species evolve to communicate in different frequency ranges - like nature's version of radio channels. When we lose species, we're not just losing individual voices, we're disrupting this incredibly complex network.

So what hope does Stewart offer? Because this all sounds pretty bleak.

Well, he's seen firsthand how resilient nature can be. Give an ecosystem space and protection, and the sounds can return. Species can rebound. But he's clear that time is running out - we need to act while there are still enough voices left to rebuild these natural choruses.
