What are the problems and challenges we face around the world when it comes to food and the materials we use to package it? How can we produce food without causing pollution and habitat destruction? How do we eat healthily and minimise food waste?

This book is part of a cross-curricular series centred on sustainability and climate change, with hands-on projects linking science and design and technology. Interactive «Solve It!» design challenges give readers the information they need to develop sustainable solutions to the problems discussed, and step-by-step «Test It!» activities encourage them to explore putting principles into practice.
