[6][7] In History for Tomorrow: Inspiration from the Past for the Future of Humanity, Krznaric delves into the last 1000 years of world history and asks what inspiration it offers for tackling ten urgent problems facing humanity in the 21st century, including climate change, hyperconsumerism, inequality, democracy and risks from AI and genetic engineering.

Rather than simply highlighting warnings from history, Krznaric searches for positive examples of what went right alongside cautionary tales of what went wrong.

Krznaric argues that humankind, especially in the wealthy countries of the Global North, has 'colonised the future', treating it as a place where we dump ecological degradation and technological risk.

The book has had widespread public impact, including being the basis for legal rulings on intergenerational rights and climate justice.

Its core ideas have also been explored in Krznaric's TED talk,[9] and in the documentary Time Rebels,[10] made for Dutch public television.
