Discover the big ideas in conservation that have transformed the world around us.

From the first national parks, through ambitious schemes such as tackling the ozone hole, and recent global movements such as the school strikes for climate, humans have made huge progress in their plans to protect the natural world. The Greatest Ideas in Conservation takes you on a journey through the most influential environmental ideas and inventions of the past 100 years, exploring different people, projects and approaches that have helped to heal our planet.

Our world has changed beyond recognition in the past hundred years. Think Big takes a close-up look at the amazing ideas that have transformed the way we all live. Each spread explores a big idea in greater depth, explaining how it came to be and what evolved from it and assessing its impact on the world today. 'Genius' panels highlight the great thinkers behind the ideas, from scientists to inventors, environmentalists and engineers.

Each book also includes carefully selected activities designed to inspire readers aged 9 and older and encourage them to nurture their own 'big thinking' and entrepreneurial spirit.
