Master Chef judge Gregg Wallace and mathematician Dr Hannah Fry take over a restaurant and invite five special guests to enjoy a dinner party with a difference, where they will be scored on the carbon footprint of every dish they choose. Food accounts for a third of all greenhouse gas emissions, so making informed choices about what we eat is more important than ever.
Gregg is with the kitchen team preparing delicious dishes and uncovering tips and tricks we can all use to cook more sustainably. Hannah is working with environmental scientists to reveal the carbon footprint of every single item on the menu and uncovering the latest research that can help us enjoy the food we love that doesn't cost the Earth.

An alarming decline in insect populations could devastate all life on earth. What's causing it, and can anything be done to stop it?
Insects are disappearing across the world. If we lost our pollinators, we would lose 80 to 90% of the plants on the planet. That is not an option. It's the ecosystems on this planet that keep humans alive. Scientists warn us that the insect apocalypse is entirely possible.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste.
Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mind boggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

Filmmaker Ali Tabrizi initially set out to celebrate his beloved ocean, but instead found himself examining the harm that humans inflict upon the vulnerable seas. From plastics and fishing gear polluting the waters, to the irreparable damage of bottom trawling and by-catch, to illegal fishing and devastating hunting practices, humanity is wreaking havoc on marine life and, by extension, the entire planet. What Tabrizi ultimately uncovered not only challenges notions of sustainable fishing but will shock anyone who cares about the wonders of ocean life, as well as the future of the planet and our place on it.
From the co-creator who brought you the groundbreaking documentary Cowspiracy comes Seaspiracy, a follow up that illuminates alarming -- and not widely known -- truths about the widespread environmental destruction to our oceans caused by human behavior.

We face one of the greatest challenges in the history of humanity, to eliminate the fuels that have driven progress and technology for over a century, while our thirst for energy only grows. The sun is the biggest source of energy in the solar system. It's like a nuclear reactor in the sky, and it provides endless power. If we can harvest just fractions of this, it can power all our consumption. Innovators are searching for new ways to capture more of the sun’s power, and make it available through the night, everywhere.

A new force threatens our perfect planet. In the past, five mass extinction events were caused by cataclysmic volcanic eruptions. It was not the lava or ash that wiped out life, but an invisible gas released by volcanoes: carbon dioxide. Almost every part of modern life depends on energy created by burning fossil fuels, and this produces CO2 in huge amounts. Humans are changing our planet so rapidly, it’s affecting earth’s life support systems: our weather, our oceans and the living world. The greatest change to be made is in how we create energy, and the planet is brimming with natural power that can help us do just that. It’s these forces of nature - the wind, the sun, waves and geothermal energy - that hold the key to our future.
Through compelling animal-led stories and expert interviews, we discover how CO2 is destabilising our planet. We meet rescued orphaned elephants in Kenya, victims of ever worsening droughts, and join ocean patrols off the coast of Gabon fighting to save endangered sharks. In the Amazon, we witness wildlife teams saving animals in the shrinking forests, and in San Diego we enter a cryogenic zoo preserving the DNA of endangered species before they become extinct.
