If man were to look at the Earth from a distance, he would probably realise the fragility and sensitivity of life and nature on Earth. Earth is a very rare and special place compared to other planets visible in space, because it contains the conditions necessary for the existence of life, such as liquid water and atmosphere. Therefore, from a distance, one can recognise the impact of depletion of natural resources, climate change, pollution and other man-made problems on our planet. At the same time, one can also see how destructive the wars and conflicts, discrimination and destructive behaviour of people around the world against each other can be. Looking from a distance can help people to realise the limits of our planet and that its resources are not infinite, and to develop an awareness of the need to use natural resources in a sustainable way.
