Insect Extinction? May 28, 2019

Show notes

Insects are the most varied and abundant animals outweighing humanity by 17 times, yet they are in decline in many parts of the world. Insects have been called the ‘glue’ in nature and are essential for the proper functioning of all ecosystems as pollinators, food for other animals, and recyclers of nutrients. This month the United Nations IPBES report said insect abundance has declined very rapidly in some places, and the available evidence supports a “tentative” estimate that 10% of the 5.5m species of insect thought to exist are threatened with extinction.

Leading entomologists tell Tom Heap that insects have an image problem when it comes to conservation and the first step is getting people to care about these little creatures. We hear about the weird and wonderful world of some insect species that are declining in the UK, including mayflies and dung beetles and discover just how they contribute to the systems we humans rely on. The conversion of natural environments to create farmland is one of the main causes of the decline, with the use of pesticides, urbanisation and climate change also major factors. Tom asks global pesticide manufacturer Bayer about what they’re doing to help reverse insect decline and considers how we can practically make more space for insects.

Eco Anxiety May 14, 2019

Show notes

Is the future of the planet making you depressed? Do you feel paralysed, unable to imagine the happiness of future generations? As global governments fail to respond to the existential crisis of climate change it’s understandable that some people seem unable to conjure up a sense of hope, understandable that dozens of young British women have joined the Birthstrike movement, refusing to bring more children into the world. Verity Sharp meets the eco-anxious and asks if they are ill or simply more perceptive than the rest of us.

The Youth Are Revolting Apr 30, 2019

Show notes

Greta Thunberg and the global youth strikes for the climate have directed the worlds attention to the potential future they face on a warming planet. The words and actions of these young people have been noted by global leaders and promises of change have been made but for their efforts to have a lasting impact the promises need to become policy. Tom Heap asks one of the young organisers Tom Bedford if young people are really changing the narrative on climate change.

The strikers' demands that the UK government recognises that we are living through a climate emergency has been taken up by some local councils whilst in the US proposals for a 'Green New Deal' are being taken seriously and Greta Thunberg has been nominated for a Nobel Peace Prize. It seems young people's hope and energy is having an impact but to really change the planet's trajectory they need to bring more of their generation with them and convince the rest of society that their future demands sacrifice today.

The Wolf is Back! Apr 09, 2019

Show notes

Wolves were hunted out of many European countries over a century ago. In recent years they've been migrating back naturally and have now reached every country in continental Europe. Not everyone is happy - while their preferred food source is said to be deer and wild boar the killing of sheep and goats has angered many farmers. Tom Heap travels to the French Alps, meeting farmers to see if its possible to rear livestock alongside a wolf population and hears about projects to help - including an innovative scheme where volunteers camp out to protect the sheep. Tom's taken his own camping gear in the hope of getting closer to these creatures and hearing or possibly seeing them. He also travels to the Netherlands. Even here, they've had sightings of wolves since 2015, so he's going tracking in one of the areas they've been spotted - hoping for a sighting or a sign. Tracks or scat can give important evidence and may help indicate if the wolves have now settled here. How will the first resident female wolf - or eventually pack - for 140 years change life for the Dutch? Join him as they wait for important news.

Fast Fashion Slow Down Apr 03, 2019

Show notes

Fast fashion is responsible for more emissions than shipping and aviation combined and by 2050 could account for a quarter of the world’s carbon budget. Consumers have been informed about the ethical alternatives but whilst sales of more sustainably sourced clothes are increasing, the biggest success of 2018 was a fast fashion brand which often sells dresses for less than the cost of their postage.

After grilling the fashion industry, the House of Commons Environmental Audit Committee has recommended action to curb throwaway culture at an industry level. But can regulation really change a nation of shopaholics who buy more clothes than the people of any other country in Europe? Lucy Siegle finds out how social media has fuelled a huge increase in consumption and how regulation, industry leaders and new generations of consumers and campaigners may finally force the industry to curb its excess.

Dash from Gas Apr 02, 2019

Show notes

Around 90% of homes in Britain get their hot water and heating from gas-fired boilers. There are 23 million of them in Britain. The Chancellor has banned them from new homes after 2025 and by 2050 they'll be history. The government is committed to phasing them out to meet international climate change commitments.

So what are the alternatives to the gas that's provided reliable, reasonably priced heat since it was first piped ashore from the North Sea in the late 1960s? Electric heating is a quick and easy replacement but we would need to massively increase the amount of green electricity that we generate. Hydrogen gas could be burnt in home appliances but producing hydrogen takes a lot of energy and expensive new infrastructure would be needed.

Peter Gibbs is on the hunt for solutions, basing himself in the valleys of South Wales where energy companies and their customers are trialling new fuels, new smart technology and new payment methods to cut the carbon from heating our homes.
