The Eden Project was built around the theme of people's dependence on plants and the natural world. This theme has only become more relevant over the years as how to respond to the full range of environmental challenges has become the most urgent shared issue across the world.

The Eden message is one of our dependency on the natural world in order to first help people realise why we must change the way we currently live. Secondly, the Eden message is one of hope, optimism and inspiration, showing people how the necessary adaptation can be achieved in a way that is both believeable and palatable. Thirdly, Eden's insight is that whilst individual action is important it is only through collective action that we will achieve the degree of change required in the available timescales.
