Giving Multiplier

Thanks so much for sharing, @chrisgpackham.bsky.social!

Thanks so much for your support and advocacy, @myqkaplan.bsky.social!

Today is #WorldFarmAnimalsDay. We've partnered with FarmKind to help free an estimated 100,000 hens from cages by supporting The Humane League (@thehumaneleagueus.bsky.social).

We're adding 50% in matching funds!

Join us: farmkind.giving/cagefree

#cagefreeWFAD

A hen spends her life in a cage no bigger than an iPad, unable to spread her wings.

This #WorldFarmAnimalsDay, let's change that. For less than a dollar, you can help free a hen, and your donation gets a 50% boost all week long. With your help, we can free 100,000 hens.

Opinion | This Problem Is Easy to Solve

For @nytimes.com, @nickkristof.bsky.social writes that global hunger is one problem we can address. 🌍

“We have a whole set of solutions,” says Helen Keller Intl's Shawn Baker in the piece. 🍠

But without US funding, many of these solutions are no longer reaching the people who need them most. 🍽️

When cost-effectiveness falls below expectations, it can backfire and actually reduce giving.
