The climate change issue is mostly a political problem, as sustainable ways of modern living have been known for decades, created by society and politicians not caring about the global impacts of local decisions. The almost-dystopian socialmedia/pervasive-ads/misinformation/compromised-democracy internet landscape is mostly a technological problem, an outcome of computer scientists and engineers just building things without thinking of the ethics of their technology. Nobody campaigned to build facebook, like they campaigned to build another coal power plant or another highway. The nerds and politicians alike are on their way to destroy the world - one compromising our minds, the other poisoning our air.

Perhaps the original sin was not pushing for more hands-on ethics training for every child and college student.
