You got to live and let live, otherwise you are acting no different than them. Greta Thunberg chooses to repress her desires to eat meat or travel and see the world for something she sees as greater good. When she gets older, she may well decide against having children to keep human footprint on the planet smaller. I am not doing any such things myself and I don't accept rewilding as an intrinsic goal of environmentalism. I believe that humans are the apex species on the planet and, like all such species, are primarily concerned with our own thriving - which may involve conservation but not self denial.

But, I am not going to try to stop her or make her life difficult with constant needling. Just like you shouldn't stop those who are willing to constrain their own sexuality for the sake of avoiding what they perceive as spiritual pollution, just like Greta is willing to constrain herself to avoid environmental pollution. To each their own, and for some living up according to their idea of honor is a greater comfort than more direct gratification. In time, we all learn something valuable even from those we don't agree with.

Can we however agree that America and other countries that embraced Western culture are great because you can live your life as you want and observant Muslims can live their lives as they want?
