Climate change. We all thought we were gonna have to cut back on consumption, use less fossil fuels, and change our infrastructure entirely to renewable energy.
Thankfully it's not a problem anymore at all. Our wise leaders just decided to stop talking about it and instead just decided we'd speed the process up, burn fossil fuels for glorified chat bots while draining our fresh water resources.
Thankfully it's not a problem anymore. Because a problem would imply it's something that has a solution. We're far past that point. We're essentially watching this generation of our oligarchs committing a mass global genocide of the upcoming generations.
Problem solved.
