Would it help if we planted new forests, reduced our garbage output, used more renewable energy sources, invested further into water bottles and re-hydration stations, etc?
Of cours it would help to at least slightly improve the problem. But that alone is far from enough - those are the kinds of solutions that somewhat naive SJW are propagating, believing that their fellow citizens needed to only change a few minor habits and everything would be fine. The kind of people who'd even believe that China is to blame for climate change because they are polluting the air like no other country...
I try my hardest to help out, I'm even trying to use lights that are more energy efficient. What else can we do?
Why didn't you just mention that upfront? The earth is saved, you're using energy-efficient lightbulbs!
