you can click once every 24 hrs to benefit UN aid organizations in Palestine. Arab.org keeps track of these benefits and publishes transparency reports every quarter at their website here. the above link goes directly to benefit Palestine, but you can also click more benefit programs from their frontpage at Arab.org.
a lot of us on tumblr are desperate to help Gaza but have absolutely nothing to offer except our attention and our worry. we don't have money to send, we don't have the ear of the public, we don't have any influence at all. this site appears to be (i say "appears to be" because ive been on the internet and just generally alive too long to ever think anything is a sure bet) a way to summon a small amount of money out of thin air and send it where it needs to go, with zero effort besides moving your mouse or your finger. i think we can all handle that much, no matter how helpless we are otherwise.
i don't like or trust NGOs as a rule, however, UNRWA, the organization aided by clicking the green link above, is despised by Israel and has been defunded by Trump twice, which in my opinion is one of the strongest indicators it is probably actually performing some useful function in Gaza.
consider setting Arab.org as your homepage in your desktop and mobile browsers to help you remember to click, and consider setting up scheduled reblogs or making your own posts with reminders.
