Are you aware of GiveWell? https://www.givewell.org/ https://www.givewell.org/ They evaluate charities; their top-recommended charity Against Malaria Foundation can, for $5, provide an insecticide-treated mosquito net that can protect individuals from malaria for 3-4 years. It's been proven to effectively decrease incidence of malaria in regions where such nets were distributed. This is very cost-effective. Charity can be very efficient in helping people. You just have to find cost-effective charities and give your money there.
