    Upon first look, the world of business is no place for young women. And many people have told my cofounders and me that in many circumstances. Pessimistic though people are about women’s chances in conducting business, three of us female college students, without any experiences, started our business with a greatly aggressive goal: to set up a seaweed farm in North Carolina and grow as much seaweed as possible to help cut down carbon emissions (排放) and pollution filled with nutrition from agricultural activities.

In the beginning, our ideas were either ignored or mocked by the researchers from whom we sought help and advice. But we carried on with our research–if others wouldn’t provide us with answers, we weren’t afraid to try to work them out by ourselves. We experiment on species which could grow in warmer waters, and we had identified potential markets into which we planned to sell the product. We've spent the last two years setting up the first seaweed farm in NC, applying for a patent (专利) and competing with five final teams in front of the United Nations for 2 million.

Despite all of our efforts, many industry experts remained unwilling to take us seriously. But as often happens in business, the same characteristics we were ignored for were, in reality, our biggest competitive advantage. Our age gave us the strength to learn from failure, and our background as environmental scientists, rather than businesswomen, helped us find new marketing opportunities. For every 10 farmers who claimed nobody would ever want to feed their cows seaweed, we found one who was interested. For every 15 cosmetics producers who refused to answer our cold calls, we stuck to the one with an interesting idea for a seaweed lotion.

Over the course of our early business development efforts, we have had access to a wealth of resources, programs, and individuals who work constantly to help us succeed. By staying focused on bringing our ideas to light, our team has demonstrated that entrepreneurship (创业) is exactly the right place for the hopeful.
