Have you heard that phrase: from seed to garment? Probably, right? Because most natural textiles are grown in the Earth. Around 24% of textiles are made from cotton, while hemp, linen and wool all depend on soil. But how often does fashion get its fingernails into the actual dirt?
Perhaps it ought to start, because according to the UN, globally, one third soil is degraded. If we carry on like this, we could lose all of our precious topsoil in 60 years. Fashion isn't entirely to blame, but it certainly has it's part to play. 
Our guest this week is Swiss-born Londoner with a Masters degree in sustainable agriculture, who is now taking on the fashion world. Nina Marenzi runs The Sustainable Angle, which stages the Future Fabrics Expo. It's all about what she calls ‘diversifying the fibre basket’  - or rethinking fashion materials.
The Expo showcases 1000s of fabrics that can help lighten fashion's environmental footprint, from organic and eco-friendly versions of our staples, to recycled synthetics right through to 3D printed seaweed and sustainable sequins.
Nina says we need to step up regenerative agriculture, organic and circular materials, and transition to textiles that have don’t trash our soil, water and air, and don't pile up in landfills.
