We have a whole lot of problems in the world, and yes we can walk and chew gum (mostly), but trash piles is the least concerning to me. Properly disposed of e-waste is not a problem, and our dumps are not threatening to over-run the countryside. The biggest problems with generative AI from an environmental perspective is carbon production, and it seems that nuclear is being re-implemented (maybe not fast enough for climate change). Existential threats from AI are also very concerning (we will see if its a jobs threat), and include malicious propaganda, biological and chemical weapons. But there is also hope that the speed of science will increase with AI, which perhaps at least could help solve issues with climate change, even if the cleaner environment is only enjoyed by rogue terminators.
