Creating specific laws for the protection and defence of future generations or promoting the creation of institutions such as the Ombudsman for Future Generations are initiatives that must be created urgently in Europe. European society and the policies of the European Union must take a step forward and begin to see the immediate need to create these new normative and institutional projects for the environmental, economic and social protection of future generations. There is a new challenge for the current European legal order that is to recognize and impregnate with intergenerationality the new rules of environmental protection, economic and social development so that the generations that will inhabit the planet in the future are expressly taken into account. Countries such as Wales or Malta have gone ahead of their time and already have specific rules for the protection and defence of future generations and have even created the figure of the Defender of Future Generations at government level. It is time to take forward these initiatives that are already working in some EU countries and to give the European legal order an unequivocally intergenerational character as a means to achieve an end: the well-being of present and future generations. The mission to protect and defend the generations to come is one of the greatest challenges facing humanity of the present for humanity of the future.
