Food for Thought

A look at the state of global food security amid rising concerns about the world population and climate change.

In New Haven, Connecticut, a community of scientists, fishermen and foodies are redefining their relationship with the sea using 3D ocean farming. In Africa, farmer-managed natural regeneration is restoring farmland to improve food security. In Holland, scientists are racing to future proof our planet against our love of meat.

Land: Gaining Ground

The survival of people and wildlife depends on the health of the land. The economic prosperity of a country is linked to the richness of its resources. But our demand for these is destroying the land and all it harbors.

Our consumption of the earth's natural reserves has doubled in the last 30 years. Now, a third of the planet's land is severely degraded. Each year, we lose 15 billion trees and 24 billion tonnes of fertile soil. And at least 10,000 species go extinct every year.

Coping with Extremes

"earthrise" travels to southern Kenya and to Myanmar to see how the locals in these areas are coping with extreme weather.

Air: Changing the Atmosphere

Every year seven million people die from air pollution. It's the world's biggest environmental killer.

Italy is Europe's most polluted country: in 2012, more than 84,000 people in the country died prematurely owing to bad air quality. To combat this, scientists have developed a new type of photocatalytic cement that absorbs pollutants and turns them into harmless salts. 

Antarctic Sanctuary

For centuries, mankind has been hooked on the concept of a mysterious continent at the end of the world. Ancient Greeks and Romans called it "the unknown southern land" and a century ago, Captain Robert Falcon Scott paid the ultimate price on his famous South Pole expedition.

Antarctica, the planet's southernmost continent, is home to spectacular biodiversity — from emperor penguins and blue whales to krill. But climate change, oil drilling and an ever-expanding commercial fishing industry are threatening this undisturbed land and its iconic creatures.

Food: Farming for the Future

Climate change has disrupted weather patterns across the globe, destroying farmland and increasing pest outbreaks. As a result, both the livelihoods of farmers and food supplies have been pushed to breaking point.

"earthrise" sets off to South Africa and Nepal to see how some newly developed solutions are helping farmers to produce food for a growing population as conditions change.

Human-Wildlife Conflict: Learning to Live Together

A look at how locals are finding ways to coexist with their animal neighbours in Australia and Bangladesh.

Winds of Change

A look at how communities in India and Denmark have adjusted their way of living, turning it into a greener alternative.

In Denmark, see how a 100%-renewable community on Samso Island is investing in its own green society. In India, a new method of cremation is helping Hindu tradition become more environmentally friendly.

Antarctica on the Edge

Antarctica, one of the most remote and desolate locations on Earth also functions as one of the world's main cooling systems. However, after decades of greenhouse gas emissions and global warming, parts of the continent are now warming faster than anywhere else on the planet. 

Over the years, climate change has led to increased erosion of the continent, altered ocean currents and affected wildlife. Warmer currents are now flowing further south, towards the icy terrain, contributing to glacial melt, rising sea levels and drastically changing habitats.
