We humans depend on the Earth’s natural resources for our very existence so it’s vital that we take as good care of them as we can.

However, it’s abundantly clear that the environment isn’t in great shape at the moment.

In this special six-part series we explore the different factors affecting the sustainability of our natural resources, investigate what their current state is and discuss what we could be doing to take better care of them.

Smart materials are a tool that have grown in popularity in recent years. Able to change properties back and forth, these materials can be used to revolutionise everything from the clothing industry to the buildings that we live in, making our world both smarter and more sustainable.

We’re joined by Anna Ploszajski, a material scientist and writer to find out more about these materials. She guides us through shape-shifting clothes, heat-absorbing roof tiles and everything in-between.
