"just use less" is a very prescriptive line that i rarely find accompanied by concrete ideas on how to do so without huge reductions in welfare and quality of life. past some point, we must consider how highly we value the habitat of a rare lemur or something weighed against the benefit to conscious beings
the above does not exclude a reduction in our hyperconsumerist tendencies. i live in a pretty minimalist fashion and 90% of what i own was passed down from relatives or picked up secondhand. i am somewhat baffled that more people don't do this, if for no other reason than cost savings
