"Environmental justice" isn't just a new way to say "environmentalism"—it's an entirely different approach.
Environmentalism generally looks only at a single piece of the puzzle at once, like the piece about conserving natural places or the piece about not filling landfills with materials that could be recycled. Consequently, it results in solutions that only address one piece at a time without questioning the larger system.
Environmental justice, on the other hand, attempts to look at all of the pieces and seek out the injustices within the entire system, ultimately questioning the system itself when it results in things like destruction of natural places and filling landfills with recyclable materials. Consequently, it leads to solutions that work to dismantle unjust and immoral systems, recognizing that all injustice is interrelated.
