If you are looking for a reputable charity to help with the situation in Venezuela, this is one I recommend.
I’ve volunteered with them and their set up is very efficient. They use local pastors and workers already based in countries around the world when disaster strikes.
They were extremely helpful and first on the scene when the earthquakes and tidal wave hit Chile a few years ago and I remember helping my parents distribute supplies when I was a little girl and we had floods and mud slides.
Because they use people already in each country the response time is exceptionally fast and their overhead costs are lowest of any similar non profits I’ve seen.
