Philanthropists and those of charitable nature oftentimes donate their life work to improving the world. Whether it is ending poverty, fighting for world peace, or finding a cure for a terminal illness, individuals that devote their time and effort to the betterment of any cause are those that spark change in the world. Such is the case for individuals such as Norman Borlaug and James Harrison.

Perhaps Borlaug’s most well known achievement, the development of semi-dwarf Mexican wheat contributed to providing a food source for an unbelievably large number of people, more or less preventing the starvation of millions in the underdeveloped world.

James Harrison has been donating his own blood plasma nearly every week for the past 61 years due to the fact that he possessed an unusual antibody.

The antibody in Harrison’s blood allowed doctors to develop Anti-D, an injection preventing women with rhesus-negative blood from developing RhD antibodies during pregnancy.

Harrison’s blood and the Anti-D injection are credited with saving the lives of over 2 million babies, and he continues to donate to this day.
