Many thousands of years ago, the first primitive humans took a step that would change the species forever – they made the first primitive ovens.
Cooking food – and back in those days it was more likely to be a woolly mammoth than a juicy burger – changed our diet, and ultimately ourselves. Cooking was the first human act to refine food. And it’s that refining – whether by farming or processing the raw resources into something more edible – that has allowed humanity to spread across the globe.
It has fuelled the growth of human settlements, bred international trade and powered the huge cities that define human habitation in the 21st Century.
But it has created problems – with easier access to food, humanity’s population has exploded. And producing and moving the food we eat needs vast amounts of energy, contributing greatly to climate change.
How do we continue to feed ourselves without harming the planet? This will be one of the questions asked at BBC Future’s World Changing Ideas Summit in Sydney on 15 November. Watch the video above to get a taste of what will be discussed.
