Great @laurengoode.bsky.social story:
Tech Workers Are Condemning ICE Even as Their CEOs Stay Quiet

According to @unicef.org, women & girls spend 200 million hours per day collecting #water — robbing them of their time & their futures.
Where #electricity is absent, running water often is too. SELF works to close this gap through solar-powered water systems. Learn more: www.self.org/water/
