Singer's ideas have contributed to the rise of effective altruism.
He argues that people should not only try to reduce suffering, but reduce it in the most effective manner possible.
While Singer has previously written at length about the moral imperative to reduce poverty and eliminate the suffering of nonhuman animals, particularly in the meat industry, he writes about how the effective altruism movement is doing these things more effectively in his 2015 book, The Most Good You Can Do.
He is a board member of Animal Charity Evaluators, a charity evaluator used by many members of the effective altruism community which recommends the most cost-effective animal advocacy charities and interventions.

His own organisation, The Life You Can Save, also recommends a selection of charities deemed by charity evaluators such as GiveWell to be the most effective when it comes to helping those in extreme poverty.
TLYCS was founded after Singer released his 2009 eponymous book, in which he argues more generally in favour of giving to charities that help to end global poverty.
In particular, he expands upon some of the arguments made in his 1972 essay "Famine, Affluence, and Morality", in which he posits that citizens of rich nations are morally obligated to give at least some of their disposable income to charities that help the global poor.
He supports this using the drowning child analogy, which states that most people would rescue a drowning child from a pond, even if it meant that their expensive clothes were ruined, so we clearly value a human life more than the value of our material possessions.
As a result, we should take a significant portion of the money that we spend on our possessions and instead donate it to charity.
