As consumer you have an impact, at least it sets an example and gives credibility. This reminds me of "climate activists" who fly around the world in private jets to preach!
Your biggest impact is as a worker. Most of us produce more than we consume (where the excess usually becomes investor profits). We really need to produce less or our consumption won't make a difference. In the past, workers formed unions and collectively bargained with governments and employers to reduce working hours down to the standard work week we know today.
