After following a study unity in option, the Genius Technology Enzymatic, I became aware of the importance of a Science, the Biochemistry in our World. The biochemistry is present everywhere and can allow resolving several problems in the environment domains, food processing one and health. But for that, we need to form more biochemists to reply to the issues more crucial of our World. Of as much as this Science can reply to the eight objectives proposed by the UN… Then, when I received fine November a mall of Microsoft, proposing me to participate in the Imagines Cup 2009, I right away thought about the Biochemistry, a Science, What I consider to play an issue crucial in our World. But beyond the first round one, I defined the name of my team (alone): "Our hands, the Sciences and our World" I am anxious to underline that the Sciences without the hands of the MAN are nothing. And a World without Sciences is only inert things and things that move… men and women worked and work again in the technology conception, in the construction of… to allow us to use them today. I have therefore constructs my photo story of twelve photos around: Education and the research in Biochemistry, Health, by research representation in Medical Biochemistry, Environment, while taking the water example, Nutrition, while taking the bread example. It is evident that twelve photo isn’t sufficient to represent a similar Science. But this is in a way an introduction to say to the entire World: "a science, the Biochemistry, exists and sufficiently isn’t exploited. Nevertheless it can resolve several problems, of as much as one can reply to eight objectives proposed by the UN. A person, the most devoted one than she be, cannot do anything to the world-wide scale. On the other hand, the world-wide body of persons, of businesses (such as the Station of purification water of Pierre Bénite, the Grand Lyon, the Mill Joseph Nicot, to come, GFC-construction…), of universities (such as the University Claude Bernard Lyon 1), Engaged in the investment for a World better, are able: * To Let the behaviours change, * To Convince the leaders of the entire World to construct a world better on our Earth, and not, on another Planet (because one is polluting it ours in a irreversible way). This is not too late; we again can act, if we do it all together…
