  •  
    The ocean's value has been estimated as high as $24 trillion, yet despite its inherent connections to the health and well-being of wildlife, humans, and the global economy, it continues to be overexploited and polluted. Plastic pollution and shark killing are two major problems that could be - at least in part - alleviated by new materials: a seaweed-based biodegradable plastic packaging, and a sugarcane-based alternative to a widely used moisturizer normally derived from shark liver oil.
