Unfortunately, without fear and the resulting public pressure, nothing will change. That used to be what drove change in the past: scientists raised the alarm, activists followed up, politicians acted. When acid rain was an issue, politicians regulated sulfur content of fuel. When the ozone layer got a giant hole, they regulated CFC gas production and usage (by almost completely banning both). When species got threatened, they got under special protection statutes, some of which more-or-less globally banned trade of them (e.g. ivory, whale and dolphin products).
Today? Scientists have raised alarm about a lot of the issues I listed. Even the rise of Trumpian authoritarianism, the threat of Putin invading Ukraine or Putin using gas dependency as a weapon against Europe was foretold. But politicians openly sharted on these predictions, they did nothing at all to prepare, and as a result societies were caught pants down. Even on this very forum we're discussing on, people are regularly acting like COVID isn't a crisis or that following libertarian "free speech" interpretations is harmless and won't lead to problems despite evidence to the contrary being available just one Google search away.
Science denialism has become commonplace, and I think this is what depresses me the most about our future. We have so many tools, almost every person on this planet has access to the entire knowledge of humanity in their pants pocket, and yet so many people refuse to do so for ideology, religion or out of simple foolishness and arrogance.
