Much of the world used to be covered with trees. But most of the world's ancient forests have been cut down.
Whether through clearing of land for agriculture, legal or illegal logging, or expansion of human living spaces - deforestation has had a broad impact on our planet. Many human populations and animal species depend on forests, while the trees themselves have even become threatened or endangered.
Ghana is one of the tropical countries that has suffered the most from deforestation in recent years. The area covered by forests has shrunk five times in 100 years. While the government promises measures, young people are seeking collective action to reverse desertification.
From shocks to industrial agriculture in the face of a dramatically changing climate in the US' Midwest, to a big bank funding rubber plantations in the Congo Basin, and lastly, the growth of the global denim market, we hear about some of the environmental costs of farming, finance and fashion, as well as attempts to reduce the industrial footprint — and whether those can be trusted.
Carmakers like VW, BMW, Daimler, PSA and Renault have been linked to Amazon rainforest deforestation in a new study. It said the firms may be using leather from cattle raised on illegally deforested land for their seats.
From species extinction to waste, land degradation to climate change and pollution, from Kenya to Australia, India, and France, this two-part special explores some of the most urgent environmental problems facing the planet — and how they might be solved. In part two, we hear about deforestation in Kashmir, puzzling water scarcity in Kenya and attempts to reduce severe air pollution in Delhi.
From species extinction to waste, land degradation to climate change and pollution, from Kenya to Australia, India, and France, this two-part special explores some of the most urgent environmental problems facing the planet — and how they might be solved. In part one, we hear about the struggle to save a native Tasmanian species from extinction, plus: French solutions to a sickening waste pile.
In Bolivia, an indigenous group known as the Yuqui, has been grappling with problems linked to life in the modern world. Like protecting their identities and their relationship to the land from outside interference. And then came Covid-19, a virus which threatens their very existence.
Trees are often seen as something to be chopped down for economic gain or cleared to make way for development. But without them, scientists warn, humanity loses an important lifeline. These carbon sinks can be thought of as giant air conditioners that cool the planet — a powerful tool in mitigating climate change. From Costa Rica to Brazil, Rome to Madrid, we hear about the state of our trees.
Over the past 40 years, around 1 million square kilometers of the rainforest have been destroyed across South America.

Sebastiao Salgado, a well-known photographer and forest champion, and musician Gilberto Gil hope to plant 1 million trees a year. Sonya Diehn presents a report by Ivo Marusczyk.
They’re Australia’s climate change refugees and they’re looking for somewhere to roost. But their smell and nocturnal shrieks have made them unpopular with locals. Scientists warn against trying to get rid of flying foxes, calling them the ‘canaries in the coal mine’ for what will happen to other species as temperatures rise. Their disappearance would spell disaster for forests and woodlands.
