I learned about a few very valuable organizations to efficiently maximize the effectiveness of your donations. I will go back thru notes to select the best. For me 1/4 of the course was 5+, as the essential need to give and most effective ways. Would have liked more ways to evaluate causes that interest you, even if not the "best" use of your donations (helping people become more independent, educated, reduce slavery, sex trade & abuse, rather than "just" focus on saving lives. Some harshness, but truth to Professor's Singer's belief: If you know about the problems you are obligated to help. So many are "blissfully" ignorant, or self-deluded by what difference can I make with the Gates Foundation & others barely making a dent. Some of my wanting to get to just the nuggets (best websites to gauge effectiveness of charities (vs administration costs) and "best charities" is because I'm retired & would like to both help while I can, but hopefully inspire my grand-kids to both know about poverty and violations of human rights, but feel that they can make a difference and to feel good about doing what they can.
