I believe very firmly that one person can change the world. For example, doctors have cured diseases and discovered life saving vaccinations that have saved millions of lives. Research shows that when one person influences a few others there are two major effects. 1. The ripple effect-this is based on the understanding that we are all connected. Like ripples expanding across the water when an object is dropped into it, one person can actually impact thousands over generations. 2. The broadening effect-this means that one person can influence many like multiplying tree branches. In my research, I discovered the following information that supports my thesis that one person can change the world. A tremendous advance in hydration was invented by David Nalin, along with his colleague Richard Cash. Dr. David Nalin discovered a treatment for patients with cholera in 1968, while working in refugee camps in other countries. By simply mixing water, salt, and sugar, child deaths from cholera dropped from 5 million to 1.3 million. Statistics show that this doctor alone has saved about 50 million lives to date. Cholera is an intestinal infection that’s rare in the United States currently. But in the developing world it’s a serious problem, with 3 to 5 million cases every year worldwide, according to the World Health Organization. The disease brings on diarrhea, which can kill a person if he or she is not properly hydrated. Dr. David Nalin won the Pollin Prize for Pediatric Research and the Prince Mahidol Award, a.k.a. Mahidol Medal winner. Dr. Nalin has saved so many lives with just a simple solution. This just goes to show that one person can make a difference in the world. CEO Steve Jobs, creator of Apple, said, “I want to focus on how one person can really make a difference by influencing thousands of people or even an entire industry.” Not only is he the Co-Founder of Apple, he is also the majority shareholder of Pixar. Steve Jobs’ vision of a “computer for the rest of us” sparked the PC revolution and made Apple an icon of American business. But somewhere along the way, Jobs’ vision got clouded, some say by his ego, and he was outed from the company he helped found. However, few will disagree that Jobs did indeed advance Apple’s growth, yet without him, the company lost its sense of direction and pioneering spirit. After nearly 10 years of plummeting sales, Apple turned to its visionary founder for help, and a little older and wiser Jobs engineered one of the most amazing turnarounds of the 20th century. Nobel Prize winner Mohammad Yunus, believed you could make a difference by starting small. Yunus helped poor people get business loans to expand or open their own business. He started with just $27 in his pocket. Yunus is known for pioneering the concept of microfinancing. These loans would go to entrepreneurs too poor to receive real business loans. Muhammad Yunus’s vision is the total eradication of poverty from the world. ‘Grameen’, he claims, ‘is a message of hope, a program for putting homelessness and destitution in a museum so that one day our children will visit it and ask how we could have allowed such a terrible thing to go on for so long. This work makes us rethink the economic relationship between the rich and the poor, their rights and their obligations.Everyday people do things that are small acts of kindness that encourage others to be kind. Research shows that random acts of kindness increases feelings of happiness and positivity. Mother Teresa said, “I alone cannot change the world but I can cast a stone across the water to create many ripples.” In 1950 Teresa founded the Missionaries of Charity, a Roman Catholic religious congregation which had over 4,500 sisters and was active in 133 countries in 2012. From these examples, I believe I have proven my thesis statement that one person can change the world and make a difference.
