Hellen Keller: 30,000 Vitamin A supplements, 10 lives saved
New Incentives: 200 vaccinations, 6 lives saved
Malaria Consortium: 3000 children protected, 10 lives saved
With only 1,000 dollars, I would donate to Hellen Keller International because of the high cost-effectiveness of the charity.
Other issues I would like to consider include biodiversity losses and human rights interventions
