Today's mass tourism and the deterioration of some buildings due to damp threaten to make Venice uninhabitable. It is calculated that, by 2030, the historic centre will be devoid of residents, while its streets will be invaded by more than 20 million tourists visiting the Italian city each year: overcrowding that poses a threat to the sustainability of a key sector of its economy.

Resource management, responsible consumption and sustainability will be crucial to ensuring everyone can live together in an increasingly globalised world, with more opportunities but also more threats.
