"Future generations" have become an integral part of discussions about sustainability. This stems all the way back to the very definition of sustainable development in the Brundtland Report, but has gained new significance with the explosion of youth environmental movements we’ve seen in recent years. The general public seems to agree that future generations should be taken into account in political decision-making processes: More and more people are understanding that their children’s or their grandchildren’s lives are under threat because of our decisions and lack of action on environmental degradation, climate change, and other sustainability challenges.
