Land-based food production is in crisis - driven by climate change & population increase. We have to grow 70% more food by 2050 to accommodate 2 billion more people on the planet (World Bank 2017). So with the oceans covering over 70% of the earth's surface surely there must be opportunities for food production there? We know fishing with large nets hasn't worked, putting fish stocks under a lot of pressure. And fish aquaculture has many negative impacts too. But today's guest Bren Smith from non-profit GreenWave is pioneering a new technique known as 3D ocean farming which is a no input, ecosystem restoring, carbon-storing innovation that could provide sustainable, affordable food and millions of jobs in the process.
