The idea of climate change violates scripture of all three Abrahamic faiths. So they will reject the idea of climate change wherever it is mentioned on ideology alone.
The science of climate change has also been adopted by “the left”, so the political right must stridently oppose its existence it wherever it is mentioned, on principle alone.
That’s a majority of the population, right there, that will openly reject climate change in every way right up until it starves or kills them.
Sure sounds like labour to me.
And there is no requirement for labour to generate income immediately. A majority of labour is front-loaded, with income being back-loaded.
Server maintenance and updating code to work with current releases is still “labour”. Because sure as shit you’ve been doing these things… no hosting provider is going to let you go 10 years with zero updates or patches to the website or the underlying framework that allows the website to run. Because failing to do that is how entire hosting platforms get rooted and infected with malware.
