This week’s programme is a thought experiment: What would the world be like if energy became superabundant and very cheap?Energy is vital for every aspect of our society, and the energy cost of extraction, processing, manufacture and transport is priced into every product we buy. Today’s energy crisis is having a huge impact, from affecting diplomatic relations between nations to the availability of food. How can our energy systems evolve and what could cheap abundant energy mean for us, our relationship to the natural world, and each other?We discuss these issues and more with;Rachel Kyte CMG, Dean of The Fletcher School at Tufts University, who has previously worked for the UN on sustainability issues.Jim Watson, Professor of Energy Policy at UCL. He’s advised government on the low carbon energy transition.And Dr Hannah Richie, Head of Research at Our World in Data, based at Oxford University, who looks at food, agriculture and energy in relation to global development trends.

Defra, the department for Environment, food and Rural affairs, released its latest Environmental Improvement plan this week. Many environmental groups have criticised the plan for having vague commitments, and landowners are asking where the money is going to come from if say farmers are going to move land out of production and into conservation. For a view away from these vested interests we’ve turned to the Office of Environmental protection – the body set up after Britain left the EU to scrutinise government environmental policy. Chief Executive Dame Glenys Stacey, and Chief Insights Officer, Professor Robbie McDonald. Last week the UK passed an emergency exemption allowing sugar beet farmers to use a controversial neonicotinoid pesticide called Thiamethoxam. This is the third year in a row that the exemption has been in place and the decision came just days after the EU banned such exemptions across Europe. A discussion in parliament yesterday saw MPs criticise the move due to the impacts of neonicotinoids on already crashing Bees populations. We spoke to Dr Richard Gill at Imperial College London about exactly how these insecticides impact bees. There are volcanic islands dotted across the globe but exactly what caused their formation and how might they change in the future? Professor Ana Ferreira at University College London is a seismologist leading an ambitious study to measure deep vibrations and disturbances around volcanic islands in the Atlantic Ocean. She told us about the challenges of recording from the ocean floor and the other unexpected disturbances they detected. As humans our eyes are one of our most valuable and expressive social tools. The whites of our eyes or sclera enable us to follow each others gaze and look our for minute changes in mood, a feature that until recently was thought to be unique to humans setting us apart from animals in our ability to communicate. But Anthropologist Aaron Sandel at The University of Texas in Austin has noticed that white sclera is in fact present in one of our closest relatives; the chimpanzee.Presenter: Gaia Vince Producers: Julian Siddle and Emily Bird Inside Science is produced in Collaboration with the Open University

What if all schools offered only plant-based options for 3 out of 5 lunches a week? Would that be enough to trigger a broader societal shift to eating less meat, and allow us to meet our sustainability commitments?We’re not talking about making school dinners entirely vegetarian — just 3 lunches a week.We discuss the benefits and practicalities of such a shift with :Tim Lenton, Professor of Climate change at the University of Exeter.Economist Marco Springmann Senior Researcher, Oxford Martin Programme on the Future of Food, University of Oxford.Nutritionist Collete Fox from Proveg international an organisation working directly with schools in the UK to encourage the provision of healthier school meals. And Henry Dimbleby founder of the Leon fast food chain is now an advisor to government, responsible for drawing up national rules on school dinners.We also visit Barrowford primary in Lancashire, which has successfully rolled out more vegetarian school dinners.BBC Inside Science is produced is partnership with the Open University.
