S1 E18: Feeding the Billions

Feeding The Billions

With global demand for food set to increase by nearly 70% by 2050, sustainable food production is one of the biggest challenges for the future. The food industry is one of the most ecologically damaging industries and we will need to completely rethink its approach if we are to keep meals on the table for generations to come.

"Food is the single biggest impact that humans have on nature. We are deforesting the earth to grow more food. It's by far the biggest user of fresh water, the single biggest source of carbon dioxide emissions, and the biggest reason why we're in the middle of the mass species extinction event, the sixth that planet Earth has faced. At least a third of the world's food is currently being wasted," says Tristram Stuart, food waste campaigner and author.

Two alternative projects in Finland and Italy are paving the way for the food of the future. This episode explores potential new strategies to satisfy the growing food demand, from restaurants growing potatoes in the air to serving jellyfish as a sustainable meat alternative.

In a busy market in the Ugandan capital of Kampala, a group of women gather to cook. While the dishes they prepare are traditional, the brightly coloured stoves they cook on are new.

Turning The Tide On Plastic: Creation and Art From Waste

Cheap and versatile, plastic is used for everything. The problem is, it's also indestructible. As a result, it piles up in landfills where it leeches toxic chemicals into soil and groundwater, or ends up in the ocean affecting wildlife and getting into food chains.

Approximately 268,000 tonnes of plastic float in our oceans - that's five trillion individual pieces. If nothing changes, it is estimated that by 2050 there will be more plastic by weight than fish in our oceans.

Green Goodbyes 

Death is a messy business. In America alone, 1.6 million tons of cement and over 870,000 gallons of embalming fluid — commonly containing formaldehyde — are buried along with 2.5 million caskets every year.

“What you have here is a landfill … a toxic landfill,” says Glen Ayers of the Green Burial Committee as he looks around a traditional graveyard in Massachusetts.
