I'm sure you've heard the phrase "One man can change the World". Well Marino Morikawa, set out to change the world starting with his childhood lake. When Marino found out that his childhood lake was polluted, he felt the need to do something about it. Marino, who is a scientist with a PHD, took a break from school so that he could clean up the lake. He developed an organic solution that abstracts polluted particles and floats them to the top. This makes it easier to clean the water. According to data, 40% of the world's lakes are contaminated, so we could definitely use more people like Marino on the planet.
