Explore the technology that will save our world by making water clean and safe!

Access to clean water is vital for the survival of people, plants and animals. With a changing climate and increased demand, we need to carefully manage our water supplies. We also have some big challenges, so let's look at the technology which will help us collect and purify more water, reduce our water use and even protect areas from flooding.

The four-book series Green Tech is an upbeat guide exploring fascinating technology from the past, present and cutting-edge of futuristic development that has the potential to help solve major ecological issues facing Earth, from the climate crisis to plastic pollution and the ongoing loss of biodiversity around the world.

The series offers a balanced view of this technology, considering the practicalities, affordability, sustainability and possible unintended long-term consequences of various hi-tech solutions. It introduces the importance of behaviour change by people in richer countries, and includes technology that facilitates this. It also highlights the need for technologies that

benefit people in the world's poorest areas, who have done the least to cause the climate crisis but are already feeling its effects the most acutely.

Perfect for readers aged 8 and up.
