I definitely think that the Internet can help the climate and approach the challenge - can it right now? Not sure.
Power consumption - I think https://solar.lowtechmagazine.com/ is a pretty interesting concept for a potential scenario, that we as humans, like farming, could do and rely on natural systems and let them (e.g. solarpower) enable when things work, and when they don’t, for connection and availability from source, mainly to slow the pace down into something what we can handle.
5G - I’m curious if this is just increasing consumption of already yearly depleted natural resources or having any positive effects for tackling climate change - at all. More data, more transfer, more consumption - everything will drive a big increase of infrastructure needs and hundreds of millions of devices which will “need” to be thrown away and replaced due to their design for planned obsolesence.
Narrative - The current tech (industry) and culture (advertising) narratives keep us away from seeing the big challenges unfolding such as the sixth extinction, ecocide, chemicals threatening reproductive organs and more.
It’s quite interesting, what will it take on how to change these narratives? Human centric Internet to me might not be sustainable if I consider what the natural capital can handle. If all humans are to use the Internet, what are the absolute necessary need that humanity and natural resources can handle? I believe it’s basic text messaging and perhaps voice calls. Not sure ecosystems can handle (or need) much more until we’ve found ways for biologically renewable technology shaping our devices and renewable energy sources to provide all electricity needed?
