On The Green Fence

Lab-grown meat could help us decarbonize agriculture and abolish factory farming along with all its environmental and ethical downsides. So why the holdup?

The world is going to need about 50% more food by 2050. Has the time come to roll out genetically modified crops that promise higher yields, are more resilient to climate change and reduce the carbon footprint of farming?

Russia's invasion of Ukraine is threatening global food security and supply chains. The shocks to food systems are set to intensify amid climate change. Is greener farming the answer?

Water scarcity already affects about 40% of the world's population and droughts could put up to 700 million people at risk of displacement by the year 2030. Are we entering a new era of violent conflict over water?

The Rhine used to be a heavily polluted and stinking river. Today, it supplies over 30 million people with high quality drinking water. How was this achieved? And which new threats are emerging for Germany's longest waterway?

As global demand for water continues to rise, safeguarding the water supply will likely grow more challenging and costly. Is more privatization the answer?

Of all the world's water-stressed countries, India has the highest population at risk. But despite shrinking water reservoirs and dire warnings that the country could soon run dry, not all Indians are taking this existential threat seriously. Why not?

The psychological impact of climate change is growing across the globe. But how do you know whether you have eco-anxiety and what can you do to keep it at bay?

By 2050, half the world's population could be affected by at least one allergy. Is climate change to blame?

Disease-spreading mosquitoes kill more humans than any other animal. They are responsible for 1 million deaths per year. Global heating will expose half the world's population to dangerous mosquitoes by 2050. Time for drastic measures?

The health care sector is responsible for about 5% of global greenhouse gas emissions. It is contributing to climate change, which will create more patients and yet more emissions. Meet the German doctor who's trying to break this vicious circle by decarbonizing health care and convincing his patients of the health benefits of a greener lifestyle.

The impacts of climate change are making us sick and claiming the lives of 13 million people every year. According to the World Health Organization, climate change is the single biggest health threat humanity faces. So what would it mean for our health if we fail to meet our climate goals?

Germany's new agriculture minister Cem Özdemir has caused a stir after speaking out against junk prices in supermarkets, especially for meat - the biggest driver of food-related greenhouse gas emissions. But why is this so problematic in Germany and would higher meat prices really solve the problem?

Buying a family home is a major life milestone in many countries. But a lack of affordable housing and a desire to curb carbon footprints has led to the rise of alternative forms of accommodation, including "co-housing." Just how does this model work? And how difficult is it to get people to share their living space?

The average living space in western countries has increased dramatically over the past decades. In Germany, urban sprawl and construction projects are eating away at nature at a rate of 50 soccer pitches per day. At the same time, people here are struggling to find affordable accommodation. How can we break this trend and are tiny houses really the answer?

Climate change is expected to make heat waves longer and more severe, with catastrophic consequences for our health and economies. The International Energy Agency predicts that energy demand from air conditioners will triple by 2050. But ironically, the more we use these carbon-intensive machines, the more we contribute to global heating. So how do we break that cycle?

In Germany, nearly 40% of national greenhouse gas emissions are caused by buildings. The housing and construction sector will need to change dramatically if there is to be any hope of achieving climate neutrality by 2045. But where to start? Listen in to find out more about passive houses, sustainable construction materials and the carbon footprint of building a family home from scratch.

Three months after deadly flash floods tore through Germany's Ahr Valley, residents in the village of Dernau are looking to the future. For many, that means rebuilding homes destroyed in the deluge. But how do you build back in a sustainable way? What needs to change to make buildings more flood-resilient? And when does it make sense to move away altogether?

This time On the Green Fence is bringing you an episode from our friends at Outside/In, an American podcast about the natural world and how we use it. In their episode "Scents and Sensibility" the Outside/In team explore the origins, role and transformation of potpourri. Listen in for a unique take on this "old school" air freshener.

Growing up in a working-class neighborhood in western Germany, environmental issues had never really played a role for brothers Adnan and Burak Arslan. But when Adnan was selected to be a part of a citizens' assembly on climate change, his view began to shift — to the surprise of his friends and family.

Climate change and severe droughts have weakened forests around the globe. In Germany, where many forests are planted monocultures, about 80% of trees are considered unhealthy. What's even more alarming is that the forest dieback is also affecting younger trees now. So what happens if we lose our forests? And is there anything we can do to stop it?

Germany's demographic setup favors the older generation in this year's crunch election. More than half the eligible voters are above the age of 50 and only 15% are below the age of 30. What does this mean for intergenerational dialogue and future environmental policy? Are older people in Germany really less interested in the environment than the Friday For Futures generation?

Engineering professor Günther Schuh claims to have developed one of the most sustainable e-cars in the world. But can he prevail on Germany's super competitive car market?

Most urban centers around the world are designed for cars, with significant chunks of space dedicated to roads and parking spaces. But what if our infrastructure was geared towards pedestrians and cyclists instead? Advocates say shifting away from car-centric cities could bring huge benefits to our health and climate.

Lithium is a critical component of e-car batteries. But what does this mean for the environment and just how far can we get with the world's identified lithium supplies?
