Meet two young and passionate designers, Nienke Hoogvliet and Dave Hakkens, who are utilising creative and innovative design to tackle the world's biggest environmental problems.

Bringing sustainability to the clothing industry is the mission for Nienke. While tackling the challenges of reshaping the culture of a global industry - that is the world’s second highest polluter - are huge, Nienke believes this is possible, with small but efficient measures. Through the creative applications of seaweed yarn, Nienke is seeking to get it off the beach, out of the museum and into development as a regular industry material.

Having bought 9 hectares of land in rural Portugal, Dave is attempting to build a living and functioning community with a minimal carbon footprint. The Kamp Project is an open source blueprint for a new society that anyone worldwide can adopt, implement and seek to improve.

Where many people might see problems, Nienke and Dave envisage solutions. But how realistic are their ambitions?
