    New Orleans native Keiana Cave, at the age of 18, is one of the youngest Americans named in the 2017 Forbes 30 Under 30 list. The college girl developed a molecule(分子) for dispersing (分解) oil, which she presently produces through her company Mare.

    Forbes, one of the most popular magazines in the US, released its annual 30 Under 30 lists on January 3, 2017. With 20 different categories (类别) from music to law and policy, in each area. Forbes presented 30 up-and-coming young groundbreakers (创始者) on its official website.

    Cave is comparatively much younger than those selected to her category, but this by no means discounts her exceptional ability. To  see her daughter's name on the list, Vanessa Cave-Herazo was surprised, but she said she knew it was coming because “Keiana has always been destined(注定) for great things.

    After learning about the negative effects of the oil dispersant( 分散剂) used in the Gulf Coast during the B. P. oil spill (泄露) cleanup, Cave decided to create her own dispersant. Cave raised $ 1.2 million from Chevron, an American multinational energy company, to develop her molecule in 2016.

    "It aims at certain poisons in the sea water,and breaks them up into water,”she said of herdispersant. “It is one of the few legal oil dispersants, " Cave added.

    Despite this achievement, Cave believes she has not quite yet reached success. She regards success as the amount of influence she has made on the community and the world.The creation of themolecule is an achievement,but she believes seeing her work being put to use will truly be her success.

    While Cave may have made the Forbes 30 Under 30 list early in her career, she is never going to slow down. She will make an effort to increase the growth of Mare, which is devoted to developing molecules to solve major social issues.

"Right now, Mare consists of this one molecule that I hope to expand and live up to the Forbes name," Cave said.
