"For the return of museum slippers," i.e. an indication of selected possibilities for museums to respond to trends in changes in the natural and cultural environment.

The IPCC Report on the Future of Climate Change, published in August 2021, leaves no doubt that everyone must work to reverse deadly trends. Museum institutions also share responsibility for the future of the planet, and their raison d'être also depends on it. Only a fragment of museum activities that are or may be undertaken in order to participate in saving the Earth is mentioned in the text. They concern the last and seemingly the least important link in museum activities - the shops and souvenirs offered there. The ways of thinking and organizing the sales of souvenirs were indicated, as well as arguments to counteract excessive consumerism, which was treated as the implementation of the mission and essence of museology.
