Today marks the World Day of Social Justice! Make it a point do do something today (and everyday) to promote social justice!
Social justice starts with interactions between people. While systematic change is always a daunting task, do something in your power to promote social justice; stick up for someone who is routinely treated poorly, start (or continue recycling), pay a little more for sustainably sourced goods, donate to a charity of your choosing, etc.
It is within everyone’s power to promote social justice; don’t let cynical / self-interested people convince you otherwise. Don’t let the crushing weight of the worlds injustices paralyze you into inaction; don’t allow perfection to be the enemy of progress.
