This week on the show, we visit the Pescadero Basin off Mexico's Pacific coast and shipwrecks in the cold waters of the Baltic Sea. Exploring the oceans – from tube worms to sea turtles – we look at the rich life they sustain. We'll also be asking what impact we humans have on our seas.

Bolivia has been dealing with torrential rains and landslides, but is suffering from a lack of drinking water as glaciers melt away. That's why the mostly indigenous people of the highland cities decided to take matters into their own hands and start their own local water supplies. Thomas Kruchem went to explore and began his quest in the metropolis of El Alto. His report is presented by Sue Cox.

The Amazon Basin is the largest rainforest area in the world. Countless animal and plant species are at home here as well as several indigenous peoples who still avoid any contact with the outside world. But the Amazon region is under threat from deforestation and development. The situation has become even more critical since the election of Brazil's new President, Jair Bolsonaro.

On this week's Living Planet we'll meet the Indian fishermen's wives who flexed their muscles to start their own rowing-boat mangrove tours. We'll find out why short-lived clothing could soon be out of fashion, whether local currencies help the environment and what sounds insects make.

How might Hazelnuts be damaging the planet and its residents? What about sardines? On this edition of Living Planet, we look at the unexpected impact of some foods and what our diets could look like in the future.

This week on the show, we're talking about the environmental impacts of being born, as well as dying. What strain does our current population of over 7.6 billion people put on the earth? How much is our population expected to grow, and how will this growth further stress natural resources and the climate?

Twice a year, our feathered friends make a marathon migration for warmth and food. We take some time to celebrate these birds, as well as meeting one woman who is making marathon journeys of her own - running 100 marathons in 100 days to raise awareness of the scarcity and waste of our most valuable resource - water.

Why is it taking us so long to do something about climate change? Is it all in the mind? That's what we're trying to find out in this week's episode. We speak with a psychologist and climate campaigners, and listen to a project that uses music and the sounds of nature to appeal directly to the heart and inspire environmental change.

All about greener transport around the world — from eco-motorbikes in Uganda to the cycle-mad city of Utrecht. And we talk to the man who's made Swedes ashamed to fly.

Just how many visitors are too many? The Greek island of Santorini struggles with tourism numbers it can't handle. How long until rising sea levels have completely destroyed Kenya's historic sites along its coast? And how hot is too hot? Glaciers in New Zealand have receded so much it's actually become too dangerous to hike all the way to the top.
