By that argument almost everything is. Ate some food that uses single-use plastics? Can't do that! Wanted to keep the lights on at night because it's more cozy?

By that argument almost everything is. Ate some food that uses single-use plastics? Can't do that! Wanted to keep the lights on at night because it's more cozy? Nope! Want to drive to work because it takes <10 minutes instead of 40 for the bus? Dirty polluter! Want to feel comfortable in winter instead of shivering while covered in blankets? Just think about all that natural gas! Selfish selfish selfish! You can go as far here as you want - there's always something, it never ends. If you're living in an industrialized country, pretty much everything we do to exist ends up being sub-optimal environmentally. I'm not saying people should do nothing. But taking no enjoyment in life is also not a solution.
