Future generations

Future generations are cohorts of hypothetical people not yet born. Future generations are contrasted with current and past generations and evoked in order to encourage thinking about intergenerational equity. The moral patienthood of future generations has been argued for extensively among philosophers, and is thought of as an important, neglected cause by the effective altruism community. The term is often used in describing the conservation or preservation of cultural heritage or natural heritage.

The sustainability and climate movements have adopted the concept as a tool for enshrining principles of long-term thinking into law. The concept is often connected to indigenous thinking as a principle for ecological action, such as the seven generation concept attributed to Iroquois tradition.

Economics
The financial state of people in future generations is widely debated. However, a study in 2022 revealed that a majority of people believe that the financial state of future generations will be worse than their current state. Adults were interviewed in 19 countries (Japan, France, Italy, Canada, Spain, United Kingdoms, Australia, United States, Belgium, Greece, Netherlands, South Korea, Germany, Malaysia, Hungary, Sweden, Poland, Singapore, and Israel), and the adults in almost every country agreed that the financial state of future generations would be worse.

The 19-country median was 70-27-3 (worse-better-same). The Pew Research Center was responsible for conducting the survey.

Legal rights of future generations
Most implementations of future generations focus on enshrining the rights and needs of future generations in law, in order to represent those unable to voice their needs.

Several countries have tried enshrining obligations to future generations in law. In Wales, this moral obligation is encoded as a legal duty in the Well-being of Future Generations (Wales) Act 2015 and in the role of the Future Generations Commissioner. The first commissioner Sophie Howe modeled the role, proposing a number of new policies designed for future-thinking policy in Wales, including a 2020 Manifesto for the Future. Similarly in Hungary the office of the Hungarian Parliamentary Commissioner for Future Generations was established in 2008. While in the United Kingdom, an informal cross-party parliamentary group has been established to discuss issues around future generations.

Climate litigation
The rights of future generations are increasingly being protected in legal precedents as part of the global trends in climate litigation. Future generations were the defendant in the critical defendants in a 2018 case Future Generations v. Ministry of the Environment and Others in Colombia which protected the Amazon rainforest basin for future generations.

In popular culture
The rights of future generations were the inspiration for the principle plot device in Kim Stanley Robinson's The Ministry for the Future.
