Our climate and ecology are certainly at risk, but I think the biggest threat in the world right now is the rapid rise of fascist China. They're challenging the notion that free speech and democracy are required for capitalism and economic gain.
China has grown so emboldened under President Xi that they're no longer content to just alter or buy out our media companies. They're flat out dictating marching orders to Western organizations and asking for employees that oppose their mandates to be fired. They're kidnapping foreign nationals and holding them hostage on trumped up charges. They've grown beyond stealing our ideas - now they're trying to supplant them.
That doesn't even begin to capture the things they're doing within their own borders. Surveillance state, social credit, travel limitations, Uyghur detention camps, supposed organ harvesting, Hong Kong / Tibet / Taiwan, ... In China it's actually 1984, and they're teaching the world that it works. If they win this battle, I worry we might wind up facing similar prospects in our future.

That's a little bit overblown. Want to make a bet on longbets.org? I'll happily donate to a green cause.
