I am a little, but compared to carbon emissions it’s not a big issue.
It’s a localised problem, so affected areas can solve it without needing the entire planet to agree. And we already have both political and technical solutions available to us. The only reason we haven’t implemented the fixes, is because big agriculture lobbies government successfully and it costs them no votes. But if the average voter has to stop showering because of water shortages, you can bet politicians will “solve” the water crisis in short order.
I have a twitter and an instagram - with about 5 posts on each. Ditched Facebook about 4 years ago when I realised it’s just all toxic boomers on there now. Ditched reddit when they killed 3rd party apps. So Lemmy, and a LinkedIn I only really check for work.
Ironically, I work for a small company and I handle all the social media. LinkedIn, Facebook, Twitter and Instagram.
That was me, but I also had Facebook between Digg and Reddit.
