The number of people living on earth has doubled over the last century. At the moment, a small number of these people use huge amounts of the earth's resources like land, energy and water. Unless we share these more fairly around the world, we are going to run out of resources.
Why is technology so important?
Our lives are shaped by technology. Not just new technologies like mobile phones and computers, but also the traditional technologies that we use to make food, homes and clothes. So if we are going to live in a sustainable way, the technology that we use has to be sustainable.
By thinking about sustainability when we design, choose and use technology, we can play an important part in building a better world for the future.
