Researchers also find zebra finches 20% less likely to hatch from eggs if exposed to noise pollution

Noise pollution from traffic stunts growth in baby birds, even while inside the egg, research has found.

Unhatched birds and hatchlings that are exposed to noise from city traffic experience long-term negative effects on their health, growth and reproduction, the study found.

Sewage pollutes our waterways, species face extinction. We must act fast to halt the decline – and we will

• Steve Reed is shadow environment secretary

We must not be the last generation to have the opportunity to marvel at nature.

When I was growing up, I took for granted the excitement of climbing trees in the local woods at the end of our road, sleeping under the stars at Scout camp, and exploring the micro-worlds of seaside rockpools on holiday in Cornwall. Our children and grandchildren deserve to be astounded by the magnificence of our landscapes and coastlines, mesmerised by the beauty of a robin’s song, and to splash about in the local river.

Steve Reed is the MP for Croydon North, and shadow secretary of state for environment, food and rural affairs

The songbird’s dramatic decline in an ancient Cambridgeshire woodland is a story repeated across the UK as human activity drives species towards extinction

Richard Broughton has been nosing around this neighbourhood for 22 years. He gossips about inhabitants past and present, reeling off information about their relationship status, openness to visitors, brawls and neighbourly disputes. “They used to have a big punch up in spring here,” he says, pointing out where one family’s territory ends and the next begins.

Some areas are eerily quiet, with popular old haunts lying uninhabited. “I always get a bit of a pang now, walking through here and it’s empty. It’s like walking down your local high street and seeing your favourite shops are closed and the pub is boarded up.”

As the soundscape of the natural world began to disappear over 30 years, one man was listening and recording it all

Read more: World faces ‘deathly silence’ of nature as wildlife disappears, warn experts

The tale starts 30 years ago, when Bernie Krause made his first audio clip in Sugarloaf Ridge state park, 20 minutes’ drive from his house near San Francisco. He chose a spot near an old bigleaf maple. Many people loved this place: there was a creek and a scattering of picnic benches nearby.

As a soundscape recordist, Krause had travelled around the world listening to the planet. But in 1993 he turned his attention to what was happening on his doorstep. In his first recording, a stream of chortles, peeps and squeaks erupt from the animals that lived in the rich, scrubby habitat. His sensitive microphones captured the sounds of the creek, creatures rustling through undergrowth, and the songs of the spotted towhee, orange-crowned warbler, house wren and mourning dove.

A five-day mindful adventure on the Knoydart peninsula – one of the last great wildernesses in the UK – offers the chance to fully unwind and leap into the unknown

It’s a relief to lay my rucksack down, plunge hot feet into the cool stream and pause to revel in the fairytale surrounds. Foxgloves stand tall against a cornflower-blue sky, ferns look almost luminous, the water glints in the early summer sunshine. A patch of moss-covered ancient forest provides shade, a cuckoo calls in the distance, mountains layer on the horizon.

I’m in Knoydart in the Highlands of western Scotland, one of the last great wildernesses in the UK, on a hiking and wild camping adventure. No roads cross the 22,000-hectare (55,000-acres) peninsula, a rugged place where a trio of Munros soar skyward, sandwiched between sea lochs Nevis and Hourn (poetically translated as heaven and hell). Over five days our group of eight will explore this land on foot, carrying our sustenance and shelter on our backs, led by two guides from The Living Project, Josh and Emily.

What can sound tell us about nature loss? Guardian biodiversity reporter Phoebe Weston tells Madeleine Finlay about her visit to Monks Wood in Cambridgeshire, where ecologist Richard Broughton has witnessed the decline of the marsh tit population over 22 years, and has heard the impact on the wood’s soundscape. As species lose their habitats across the world, pioneering soundscape ecologist Bernie Krause has argued that if we listen closely, nature can tell us everything we need to know about our impact on the planet
